Abstract:
An email client and file manager provides combined file management and communications management in a single interface. An interface allows documents, email messages, contact information, web links or pages, and user-attached notes to be stored in the same folders. This facilitates communication by email and fax. The interface permits the user to combine this data in folders which the user categorizes according to a folder tree created by the user. In one embodiment of the invention, the client, in its email function, communicates with a dedicated host which in turn communicates with external servers according to standard internet protocol.

CROSS REFERENCE TO RELATED APPLICATION 
     This application is a continuation of U.S. patent application Ser. No. 09/908,983, filed Jul. 19, 2001, which claims the benefit of priority from U.S. Provisional Application No. 60/219,294, filed Jul. 19, 2000, the disclosures of which are hereby incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to information processing system organization and in particular, to an interactive user interface to information processing systems. More particularly, the present invention relates to an activity-oriented user interface that allows a user to create and define customized groupings of several kinds of different objects created by information processing, communication and/or web applications, as opposed to the prior art of grouping like objects together in separate and distinct object groupings. 
     BACKGROUND OF THE INVENTION 
     A computer screen user interface provides the user with certain tools to organize the objects he or she is working with. The most common and typical way of organizing the objects in a computer is a hierarchical structure of directories or folders (hereinafter called folder structure). The user interface typically includes some default initial folder structure, which the user can eventually change by adding new folders and subfolders. Such default or user defined folder structure is used to simplify finding, retrieving and working with the objects, provided the user employs and memorizes certain individual conventions and rules, when the user creates, saves or moves the objects to certain folders or subfolders. Typically, the user tries to create and name folders and subfolders in such a way, that later, whenever necessary, it would be easier for him or her to understand, memorize or logically deduce, what kind of objects should be saved to or retrieved from, a certain folder. An example is the Microsoft Windows Explorer, which presents a folder structure and contents of each folder. 
     In addition to the folder structure, typically there is a special location, such as a desktop, root directory, special folder or location bar (hereinafter called desktop), to store most frequently used, new, temporary or uncategorized objects. For a reasonable number of objects, such locations provide a faster access for the user. Therefore, as the number of objects in such desktop grows, all but a limited number of the most frequently used objects should be eventually moved into the folder structure. The examples are Microsoft Windows Desktop, which can contain a certain spatially limited number of object icons, and the default My Documents folder in Microsoft Windows 95/98/2000. 
     In addition to the folder structure and desktop, some computer applications, software or programs (hereinafter called applications), provide their own default locations to store and retrieve user&#39;s objects, with or without folder structure, with or without user&#39;s capability to manipulate such folder structure, and with or without access to the general folder structure or desktop. In such cases the user has to organize his or her objects, using a separate set of rules and conventions, specific to such application, and in some cases an additional effort is needed to find, retrieve and work with these objects, other than through such particular application, if it is possible at all to do so. In addition, some applications allow access to the general folder structure for some types of objects, but not for the others. An example is Netscape Messenger, all versions up to the present date, which, for storing email messages, provides its default folder structure, which can be manipulated by the user. Netscape Messenger allows saving some types of objects, such as attached document files, but not the email messages themselves, in a general folder structure. Other examples are Netscape Navigator and Microsoft Internet Explorer, which allow storing the bookmarks or favorites respectively within a special folder structure, but not in a general folder structure. 
     There are several problems with the above prior approaches. In order to use Windows Explorer to organize objects, the user must be aware of it and learn about its features. Windows Explorer doesn&#39;t open automatically, and is merely included as one of many other components of the Windows operating system. Furthermore, Windows Explorer, once opened, doesn&#39;t clearly show the features of creating, renaming and manipulating the folders, those features being initially available from inside the cascading menus. As a result, many users, especially novices, cannot easily organize the objects they work with, and waste extra time and expend extra effort to find objects, sometimes unsuccessfully, and in general fail to use the computer in an efficient and convenient way. 
     In contrast, the Windows Desktop or default My Documents folder are presented very evidently in the user interface (the latter by being a default save location for some applications), and many users, especially novices, use them to store the objects. However, as mentioned above, eventually these locations become cluttered, and, without inherent hierarchical structure, inefficient in organizing the user&#39;s objects, as they grow in number. 
     Among the various types of computer usage, the most common for a computer user are: information processing (e.g. documents, files), communication (e.g. email, messages, contacts), web browsing (e.g. websites, bookmarks). Email clients and web browsers, which handle the second and third types of usage, do not use the same general folder structure-nor do they allow the user to organize the objects they generate into the same general folders—as are used with the information processing, with a few particular exceptions for some specific types of objects. Instead, the user is presented with a specific separate folder structure for each type of the object. 
     The email clients provide the user with two specific folder structures, one for the email messages, and another one for contacts and email addresses. The document attachments to email messages, however, can be stored in a general folder structure. 
     The web browsers provide the user with a specific folder structure for bookmarks or favorites. However, the individual bookmarks or favorites subfolders can be saved or copied to a general folder structure. 
     Not being able to use the general folder structure for all types of objects requires a user to create a multiplicity of several separate folder structures. In addition, a user must maintain and memorize separate folder structures in order to organize the most common everyday objects. Very often, these different types of objects relate to one activity, project, client, matter, etc. as categorized in the mind of the user. For example, if the user is working on a certain Project A, he or she very likely has a number of files and documents related to project A, plus a number of email messages related to project A, plus a number of email addresses for contacts involved in Project A, plus a number of Internet bookmarks for Project A. The prior systems and methods require the user to look for and work with these four types of objects in four separate and different folder structures. Even though the most organized of users may try to coordinate and conform the four different folder structures, every time the user looks for a different type of object, she still needs to access another folder tree, even if conformed. Typically, though, each of the four separate folder structures would be created at different times, and would contain more or less detail than the others, have different names for the folders and subfolders, and as a result, display a great deal of nonconformity in the different objects that are nonetheless related to the same user activity. Efficiency in processing different types of objects within the same activity demands the user to memorize several folder structures, their folder and subfolder names, and consistently follow rules and conventions for each in storing and manipulating the objects. As the number of activities, projects, clients, tasks grows, so does the burden and inefficiency in maintaining parallel folder structures. 
     In addition, inability to use the same folder structure for all objects of the same activity leads to other inefficiencies in using the computer besides an increase in file maintenance. For example, an email message with an attachment may contain at least three different types of objects: a contact name and email address; text message in the body of the email; and one or several attached files. Except for certain limited numbers of attached file types, which can be viewed inside the email (i.e. images, html documents), the attached files are opened by other applications, which files may be edited and then must be saved in the general folder structure, while the original email message remains in the email folder structure. This separation of the e-mail into different objects has several drawbacks that the present inventors have identified: (1) It is hard for the user to delete an attached file without deleting the text message, (2) Disk space is wasted by keeping two copies of the same attached file; one in the email client and one in the general file structure, (3) The general folder structure fails to contain information about senders/recipients of the attached file. 
     As referred above, a disadvantage of the prior email clients is that they indicate in their list of communications only the sender of the sent messages, instead of the recipient of the sent messages. In most cases, the sender of the sent messages is the user. A disadvantage of prior user interfaces is their drag-and-drop technique by which a user directs a mouse to move objects within the folder structure and the interface in general. A user has to keep the mouse button pressed while navigating the interface. If a user ceases to press the button during a command operation, he or she loses the ability to complete the operation and has to start all over. Such movement is ergonomically inefficient and taxing, especially to a user who moves objects within and across various folder structures. 
     The present inventors have perceived drawbacks to piecemeal approaches to the above problems. The present invention provides solutions, thereby giving the user advantageous ways to keep track of multiple sets of information, which otherwise would require additional physical and more complex effort. 
     SUMMARY OF THE INVENTION 
     Features 
     The present invention increases efficient use of user time and effort by providing an information processing system and method by which a user groups and accesses different kinds of objects related to the same activity together in a general user-defined folder. Specifically, the present invention provides a user interface that allows a user to group and access different kinds of objects together in a general user-defined folder. The different kinds of objects that may be placed together in and accessed from the same folder include: application files and documents; contacts such as address book entries, including e-mail addresses and fax numbers; communication files such as e-mails and faxes; web browsing objects, such as favorites or bookmarks; and web pages. 
     The prior art permits data files to be organized in a file structure. According to one aspect of the present invention, files containing activity-relevant email, URLs, documents and contact information are easily placed in a logical organization in the same directory folder, by which they are more readily associated with each other for retrieval and manipulation. The present invention lets a user store and access all of these functionalities and files directly through the same user interface so that each functionality is constantly available to the user. This is done without exiting the interface. In a particular embodiment of the present invention, manipulation of the files is accomplished without the need exit the interface in order to invoke separate program applications. 
     The methods of the present invention may be implemented in an information handling system, which includes one or more processors, memory, and input/output means. One of the embodiments of the invention is a set of instructions resident in an information handling system. 
     The present invention also provides an article of manufacture in the form of a computer-readable medium on which is stored a computer-readable software program capable of performing the foregoing method. Further, the present invention provides a computer system having preloaded therein a software program that allows a user to place different kinds of objects that he or she defines as related to the same activity together within a user-defined folder of a general folder structure. The computer system includes a processor and a display device coupled to the processor. The display device is used to display the user interface that allows a user to place different kinds of objects related to the same activity together within a user-defined folder of a general folder structure. The computer system also includes storage devices, such as a local or remote memory storage device, coupled to the processor. The memory storage device maintains the program module and data. 
     It is a feature of the present invention that application files, communication messages, email addresses and fax numbers of contacts, web bookmarks or favorites, and web sites can be stored together in and accessed from the same folder of the activity-oriented interface. 
     It is also a feature of the present invention that communications containing attachment(s) are separated on arrival to the recipient into a text message file and attachment file(s), each attachment file bearing an indication of the sender and/or recipient. A further feature of the present invention identifies such attachments with a visible icon denoted as a sticker note, which indicates the subject of the email message that the attachment accompanied. Text message files and attachment files are also annotated with the specific date and time received or sent. In this way, the user can relate and group within the general folder structure email messages with their attachments and yet is still able to process and perform operations on the attachments without having to so process the email messages. 
     It is also a feature of the present invention to provide visible icons by which the user can create and rename user-defined folders of a general folder structure into which the user may store together application files, communication messages, email address and fax numbers of contacts, web bookmarks or favorites and websites. The visible icons provided by the current invention presents a powerful user interface that displays a user&#39;s own folders, which a user creates to organize and group files and correspondence, along with shortcuts to installed software applications and to the utilities of the software of the present invention. 
     It is an important feature that the present invention couples the above features with a private email server. In so doing, a user, using the email functionality resident in a software program of the present invention, may send and receive emails directly within the user interface of the present invention upon connecting to an Internet Service Provider (ISP) of choice. Alternatively, a user may continue to send and receive emails from a server other than the private server, which is connected to the user&#39;s ISP server. 
     Coupled to the compound features of email functionality and the direct access of different kinds of objects within the same user-defined folder is a feature that provides automatic encryption and decryption in handling a user&#39;s email messages, both transparent processes to the user. Additionally, encrypted files are compressed. Once the encryption module of the present invention is configured by the user, the user does not have to deal directly with encryption keys setup or management and is thereby freed from learning the encryption software. 
     The present invention also features automatic archiving of files or messages left by the user in the general desktop folder at the end of a work session. 
     In addition, an important feature of the present invention is a pick-and-drop technique by which a user moves objects within the activity-oriented interface. In a “pick-and-drop” technique, a user clicks a mouse button once to select an object or objects, moves the object(s) around the interface without having to keep a mouse button continuously depressed, and then drops the object(s) where needed by pressing a mouse button once again, which action de-selects the object(s). With this feature, a user, with a minimum of mouse clicks, may open a file, copy it to a different location, fax or email it, depending on the context. Using the pick-and-drop technique, a user may send a message by dropping the message onto any contact name that is displayed within the same folder. Further, a variant of the pick-and-drop technique may be used to save web links or web pages, to “drop” them to a contact file or to send them to a contact. 
     Moreover, the pick-and-drop technique is well-suited for use with portable and handheld computerized systems in that it allows a user to execute commands and operations with a trackball and touchpad with greater precision. 
     Advantages 
     It is an advantage of the present invention that files and/or communications in various forms, such as e-mails and faxes, can be sent to the contacts listed in the same folder of the activity-oriented interface. It is a further advantage that all communications have a smart indication of a sender for the received files, and a recipient for the sent files. 
     A further advantage is that an implementation of the present invention not only allows a user to avoid excessive clicking on a mouse but also does away with double clicking. Importantly, for those users relying on a mouse, the user no longer needs to continuously depress a mouse button to keep the object selected during the dragging of an object. Unlike dragging a selected object, performing an operation involving a selected object in the present invention may be interrupted (such as by a telephone call) and then may be continued. The greatly reduced mouse clicking of the present invention carries a strong ergonomic advantage in reducing injury due to repetitive stress injury. The present invention solves a problem not solved by the prior art by allowing a user to work separately on email messages and their attachments, without leaving the same activity folder. Therefore, it is an important advantage of the present invention that a user may receive, amend, add to, move and/or send an attachment from within the same activity interface without having to access different folder structures of various applications first. 
     It is an advantage of the present invention that various objects left accumulated in the general desktop folder at the end of the last working session will be automatically placed into a general archive folder and are either retrievable by subject, sender/recipient or date and movable back to either the general desktop folder or any old or new folder, or may be deleted. 
     A further advantage is that, for users traveling with a portable computing system who need to store and maintain various kinds of objects while on the road, the present invention facilitates synchronization of files. By maintaining all the different objects a user may need to use on the road in one folder location, known and defined by the user, the present invention makes copying between computing systems or devices less burdensome as well as creates identical folders on different computing systems or devices, thereby reducing loss of information and maximizing efforts spent on file maintenance. 
     These and other objects, features and advantages of the present invention may be more clearly understood and appreciated from a review of the following detailed description of the disclosed embodiments and by reference to the appended drawings.

     DETAILED DESCRIPTION 
     Definitions 
     Object. A current paradigm used for designing and implementing the present invention into a software program is object-oriented programming, which defines and packages objects. An object consists of a data structure plus the operations available for that structure. Once objects are defined, it is possible to build a program as a simple sequence of processes to be performed on specified instances of the objects. An integral part of object definition is the ability to create new, more elaborate objects as enhancements of those previously defined. 
     Activity. A user-defined class of related files whereby a user lumps together different categories of information stored and accessed from different files into a conceptual whole and classifies the whole as a project, task, operation, etc. An activity is a user-defined folder that contains related files which were each not created from the same application programs. 
     Activity-oriented interface. A user interface, which may be icon- and/or menu-based, by which a user can create, manipulate, store and access various kinds of program application files from within the same folder. 
     General folder structure. The most comprehensive arrangement of hierarchically nested folders so that all folders are contained and organized within. The folder is part of the directory structure, known as a tree directory structure. Therefore, for the purposes of this description, a folder is the equivalent of a directory. Each folder or directory may contain one or more files and may contain one or more folders or subdirectories. 
     Operating Environment Variations 
     The following discussion together with  FIGS. 1 ,  2  and  3  briefly describe an example of a suitable and typical information handling environment in which the invention may be practiced. The invention is described hereinbelow in the context of an application program that runs on an operating system in conjunction with a personal or business computer processor. Nonetheless, those skilled in the art will be aware that the invention may be practiced in combination with other program modules, such as routines, programs, components, etc. that perform particular tasks. Further, those skilled in the art will recognize that the invention may be practiced with computerized systems other than that described hereinbelow, such as hand-held devices, multi-processor systems, programmable consumer electronics, minicomputers, and mainframe computers, as well as in distributed computing environments in which remote processing devices are linked through a communication network to perform tasks. 
     With reference to  FIG. 1 , a typical example of an information handling system  100  for implementing the present invention includes at least one processor  110 , a system memory  112 , which includes Random Access Memory (RAM)  114  and Read Only Memory (ROM)  116 , and a system bus  118  that couples the system memory  112  to the processor  110 . The system bus  118  also couples the basic input/output system  120  (BIOS) for connecting peripheral devices such as disk units  122 , tape drives  124  and printers  126  to the processor  10 . Moreover, the system bus  118  couples the processor  110  to the user interface adapter  128 , which is connected to various user interface devices, such as keyboard  130 , microphone  132 , a pointing device such as a mouse  134  having buttons  135   a  and  135   b , speaker  136 , and touch screen device  138 . Further, the system bus  118  couples the processor  110  to the display adapter  140 , which is connected to a display device  142 . For connecting the information handling system to a data processing network  146 , the system bus  118  couples the processor  110  to a communications adapter  144 , which may link the system of  FIG. 10  with perhaps thousands of similar systems or devices, such as remote printers, remote servers, or remote storage units. 
     With continuing reference to  FIG. 1  and now referring to  FIG. 2 , the present invention is typically implemented as an application program in an information handling system, such as a conventional personal computer system  200 , comprising processor  210 , keyboard  230 , mouse  234  having buttons  235   a  and  235   b  and display  242 . The hard drive  248  or storage device  250  contains computer program code that performs a method of the present invention preloaded or stored therein. As is well known, the user clicks a mouse button, or alternatively uses a touch pad, trackball or a touch sensitive screen, to supply input signals that move a cursor visible on the screen (or that lights up portions of the selected display). By moving the cursor over the icons shown on the screen, the user can perform desired tasks in the methods of the present invention. 
     The present invention may also be practiced by an article of manufacture using a computer-usable medium, such as a floppy disk or a CD-ROM, containing computer-readable program code configured to cause the computer to perform a method of the present invention as explained hereinbelow. 
     The information handling system  100  of the present invention or the method of the present invention or the article of manufacture of the present invention comprises in part a computer program code  500  that interacts with the computer hardware in one of several possible ways.  FIG. 3A  shows one embodiment of the present invention wherein the computer program code  500 , executable by the computer processor  110 , interfaces with an application program interface (API)  506  which interfaces with an operating system  508  which then interfaces with the hardware of the computer  502 , typically the processor, memory and hard disk drive. The operating system can comprise be virtually any of the well-known ones, such as a version of Windows (Microsoft Corporation), MacOS (Apple Computer), or UNIX or Linux, or any other operating system appropriate to the pertinent hardware and firmware, and having a known API. 
     Alternatively,  FIG. 3B  shows the computer program code  500  interfacing directly with an operating system that is able to directly interface with the computer hardware  502 , such as a version of Windows operating system, (Microsoft Corporation) or a version of the Unix operating system. Further,  FIG. 3C  shows the computer program code  500  incorporating the necessary operating system elements, so that it may interface directly with the hardware  502 . In yet another embodiment, the computer program code  500  could be written in a hardware-independent language, such as JAVA (Sun Microsystems) or JavaScript (Netscape Communications Corp.). 
       FIG. 4  shows a display  5 , which is the output of the display device  142  and which interfaces with a user. The screen real estate of the display  5  is organized into several functionality areas, including a Program Area  10 , a Folders/Contacts Tabs Area  30 , a General Folder Structure Area  36 , an Arrows Area  70  and a Workspace Area  90 . 
     The Program Area  10  comprises at least two kinds of icons: a plurality of first icons  12   a - l  and a plurality of second icons  14   a - d . Each of the first icons  12   a - l  is a graphical representation of an individual utility function. Icons  12   a - l  in the Program Area represent the following functions: Create  12   a  by which a user may create a new file, folder or address book group; Rename  12   b  by which to rename a file, folder or address book group; Duplicate  12   c  by which to create a copy of a file or address in the same folder; Print  12   d  by which to print a file; Assign Color  12   e  by which to attach a color code to a file or address; Attach Sticker  12   f  by which to attach a sticker note to a file or address; Send &amp; Receive  12   g  by which to connect to a server and to send and receive email messages; Reply to Mail  12   h  by which to send an email message to the sender of a previously received message; View With Address  12   i  by which to view files sent or received from a selected address; Configure Program  12   j  by which to establish setup parameters for connection to a private server and for automatic, transparent encryption and decryption of sent and received e-mails; Configure Fonts  12   k  by which to set up fonts used in the interface; Delete  121  function by which to put files or folders into a “trash bin” and to delete addresses, groups or program icons. 
     Each of the second icons  14   a - d  in the Program Area  10  is a graphical representation of a shortcut to a program application. This is illustrated hereinbelow in a Windows (Microsoft Corporation) environment. Shortcuts to applications function in a Windows environment by loading and invoking the selected application. The user may place into the Program area those application shortcut icons that he or she commonly uses.  FIG. 4  shows examples of the following shortcut icons:  14   a  for Microsoft Notepad;  14   b  for WinZip;  14   c  for Microsoft Word, and  14   d  for Microsoft Excel. 
     Four email functions  15   a - d  are provided in the Program Area  10 . These are Compose  14   a , Send  14   b , Add to Contacts  14   c  and Delete  14   d.    
     The Folders/Contacts Tab Area  30  comprises two tabs: a Folders Tab  32  and a Contacts Tab  54 .  FIG. 4  displays the Folders Tab  32  selected. When the Folders Tab  32  is selected, a My Documents Area  34  displays the General Folder Structure  36  shown in  FIG. 11 , when the Contacts Tab  54  is selected, an Address Book Area  56  is displayed. 
       FIG. 4  shows an exemplary default organization of the General Folder Structure  36 , which contains all applications, icons and objects available to the user on the computing system  100 . As shown, the General Folder structure  36  includes the following specialized object locations or folders: ARCHIVE  42 ; My Computer  46 ; and TRASH  48 . 
     Also shown in  FIG. 4  is the Workspace Area  90 , which displays the files and contents of a folder in the My Documents area  34  that has been highlighted and an Arrows Area  70 , which organizes the Workspace Area  90  into fields  70   a - f  that identify certain properties of the files. 
       FIG. 4  shows output from a display device without indicating a particular hardware-software configuration or operating system environment as discussed in reference to  FIG. 3 . Although  FIGS. 5-11  shows output from a display device wherein a software program of the present invention is running within an exemplary operating system environment, herein Windows, the invention as disclosed in  FIGS. 3A-C  may be practiced within any hardware-software configuration and from within any suitable operating system. 
     Referring now to  FIG. 5 , the output shows an opened TOOLS folder  38 , which comprises the following folders: Program tools  38   a , New Documents  38   b , Programs  38   c  and Windows Desktop  38   d . The program tools  38   a  are tools associated with the inventive program.  FIG. 5  shows the program tools folder  38   a  highlighted and the Workspace Area  90  displaying the contents of the highlighted folder  38   a . The program tools folder  38   a  contains the same icons and corresponding commands  12   a - l  that represent program utilities as are displayed in the Program Area  10  and as discussed with reference to  FIG. 4 . Also appearing in the program tools folder  38   a  are email icons  14   a - c . The email Delete icon  14 D is not in the program tools folder  38   a , but can be invoked from other menus as desired. A user may click on either a corresponding command  12   a - l  in the Workspace Area  90  or an icon in the Program Area  10  to accomplish the same set of utility functions. 
       FIG. 6  shows an activity-oriented user-defined folder containing different types of user objects or files. Specifically,  FIG. 6  shows that opened ARCHIVE folder  42  contains four user-defined folders: Activity A  42   a ; Activity A 1   42   b ; Hobby B  42   c  and Project C  42   d . Each of folders  42   a - d  represents exemplary activities, projects, tasks, etc. defined by a user. Activity A folder  42   a  is shown highlighted and its exemplary contents are displayed in Workspace  90  as files  44   a - m . Particularly noteworthy is that Activity A folder  42   a  has stored within it the following various kinds of files, which may be accessed by a user: Microsoft Notepad files — 44   a ,  44   c ,  44   e ,  44   j  through  m ; Microsoft Word document — 44   b : Internet web page:  44   e ; Microsoft Excel files:  44   g  &amp;  h ; e-mails — 44   f  &amp;  i.    
       FIG. 6  also displays the various icons used within fields  70   a - g  of Workspace  90 . In field  70   a  icons indicate the application that the file is associated with. In field  70   b , icons indicate whether a user has attached a sticker note to the file or color-coded it. Field  70   c  displays the user-assigned file name. Field  70   d  displays the date and time when the field was created (e.g., files  44   f  &amp;  44   g ) or sent (e.g., file  44   i ) or received (e.g., files  44   b  &amp;  44   c ). In field  70   e , the icon indicates that the file was received into the Activity A folder  42   a ; when clicked on, the icon in field  70   e  displays the e-mail address of the sender of the file (not shown). Files received into the Activity A folder  42   a  include files  44   a - 44   e , whereas files sent out of Activity A folder  42   a  include files  44   h ,  44   i ,  44   k - m . Field  70   f  displays the name of the sender or recipient of the file depending on how the file has been processed. Information in fields  70   c ,  70   d , and  70   f  that relates to files  44   b  to  44   e  is shown in italics, which indicate that these files have not yet been opened. In field  70   g , the icon indicates that the file may be sent or has been sent outside the file folder, here Activity A folder  42   a . When the icon in field  70   g  is activated, the e-mail address of the recipient of the file is displayed (not shown). 
       FIG. 7  shows an opened My Computer Folder  46 , located in the General Folder Structure  36 . As shown, the opened My Computer folder  46  displays an exemplary My Computer file structure  60 , used to identify storage locations of files saved on a storage medium, typically a disk drive or flash memory chip in a computing system. The My Computer file structure  60  as shown in  FIG. 7  is for illustrative purposes only and may include any customary file structure suitable for the computing system used and adopted by those skilled in the art as well a more tailored file structure developed for a specific user. 
     Composing 
     With continuing reference to  FIGS. 4-7 , when a user desires to create a new file while using the method of the present invention, unlike with interfaces in the prior art, all he or she has to do is to open a desired folder in the My Documents area  34 . The user is then presented in the Workspace Area  90  with a list of software applications that are currently available to the user from within the computing system he or she is using, either because the applications have been stored within the computing system or because the user has Internet access to them. When the user clicks on an application icon, that application is executed and a new document page for that application is displayed. The user may then create a new document for that application. All new documents are assigned a date and time when they are first created, which is always visible along with the assigned file name. 
     Storing Documents from a Variety of Applications 
     Once a new document has been created, a user may save it to a folder within the ARCHIVE folder  42  displayed in the My Documents area  34  of the software method of the present invention. The user saves a new document to an existent folder by activating or “picking” the file to be stored, which causes an icon to be displayed that indicates that the file has been selected. The user then moves the icon to the desired folder and then de-activates or “drops” the file by right-clicking onto the desired folder. This technique is called “pick-and-drop”. A software method of the present invention employs this technique for saving, routing and transporting files. 
     A user may save a new document into a new folder. Creating a new folder is done by opening the My Documents area folder  34  and then activating the Create New Folder icon  12   a  in the Program Area  10 . Once a new folder is created, a user can save a new document into it using the pick-and-drop technique. 
     All folders are stored in the ARCHIVE  42  folder of the My Documents folder area  34 . Importantly, a user can save any new document created with any application accessible to the user&#39;s computing environment (either stored on a hard drive or network, or used directly from the Internet) into any folder in the ARCHIVE  42 . A user is not limited to saving files created with one application into one ARCHIVE folder (see  FIGS. 5 through 10 ). In practical terms, then, a user may create a new folder, naming it for a particular activity, task, work session, project, etc., and then save into that folder all files related to that activity, etc., regardless of which application they were created with. Thus, unlike software applications or operating systems in the prior art, the present invention actually permits a user to create a user-defined activity folder and to store different kinds of files—regardless of application type—into it, especially as shown in  FIGS. 5 to 7 . 
     Storing Electronic Communications 
       FIG. 8  shows a user-defined activity folder, Activity A  42   a , that contains a received electronic communication that has been separated upon arrival by a software method of the present invention into an e-mail message and an attachment. In  FIG. 8 , the contents of opened Activity A folder  42   a  is shown listed in the Workspace Area. 
     Shown in  FIG. 8  are two related files,  44   q  and  44   r , which both show in field  70   d  that they were received at the same time. For attachments to e-mail messages (and for sticker notes placed in field  70   b  of any file), a user may position the cursor over the icon in field  70   b  to bring into view a message window that displays the name of the attached file (or the content of the sticker note attached to the file). 
     The present invention separates e-mail messages from their attached files upon arrival, while storing these two kinds of files within the same activity folder, which is not done by the prior art. A user, therefore, may process and access these two kinds of files from within the same activity folder. 
     Moreover, with continuing reference to  FIG. 8 , field  70   f  in Workspace  90  shows the name of the sender or the recipient of the file. The arrow icon in field  70   e  indicates the file was received; whereas the arrow icon in field  70   g  indicates the file was sent. 
     Sorting Electronic Communications 
     As shown in  FIG. 9 , a user, while working within a user-defined folder 
     may sort the files displayed in the Workspace  90  to include only those communication files, i.e., e-mail messages and attachments, that contain a certain contact. In  FIG. 9 , the sort was limited to those files within an exemplary user-defined activity folder, Activity A folder  42   a , that contain an exemplary contact, “Contact  2 ”, in field  70   f . Thus,  FIG. 9  shows that subset of folders,  44   e ,  441 ,  44   i , and  44   n , within user-defined Activity A folder  42   a  that contain “Contact  2 ” in field  70   f . Highlighted in  FIG. 9  is the file “Memo on Activity A ( . . . ”, which displays in field  70   f  not a specific Contact name but a LIST, which indicates that the file has been sent to more than one Contact. When a user places the cursor on the icon in Field  70   g  of File  44   n , a window message  47  is shown that indicates that the file has been sent to “Contact  2 ” and to “Contact  4 ”. 
     Sending/Receiving Electronic Communications 
     With continuing reference to  FIGS. 4-9 , a user may receive an electronics communication by activating the Send/Receive Mail icon  12   g  in Program Area  10 , which will cause a software method of the present invention to connect to a private communications server (so long as the user has configured a software method of the present invention beforehand to connect to a private server by activating the Configure Program icon  12   j ). Communication messages that the user has received from any of its registered PPP servers will appear in the Workspace Area  90  when the user activates the My Documents area  34  (so long as the user has configured a software method of the present invention beforehand by activating the Configure Program icon  12   j ). The user may then store any of the communications messages into a user-defined activity folder in the ARCHIVE  42  by picking (selecting) a message in the My Documents area  34 , positioning the cursor over the ARCHIVE  42  folder of choice and then dropping (right-clicking) the message there. To reiterate, e-mail messages and their attached documents are received by a user as two separate files, so that a user may store, process and access them as separate files within the same user-defined activity folder. 
     A user may send a communication message in a similar manner as described above. A user first creates a text message in the My Documents area  34  and then picks and drops a contact name onto the message to indicate the address to which the message is being sent. (See the description of  FIG. 11  hereinbelow). To attach a file, a user may pick-and-drop a file onto the message in My Documents area  34 . A user then activates the Send/Receive Mail icon  12   g  to connect to a private server, which will send the communication message (so long as the user has configured a software method of the present invention beforehand by activating the Configure Program icon  12   j ). 
     Encrypting 
     With continuing reference to  FIGS. 8 &amp; 9 ,  FIG. 10  shows an output display for an encryption of a communication file stored in the same user-defined ARCHIVE  42  folder as shown in  FIG. 8 , titled Activity A  42   a . An Encrypting Window  80  (also used for display of transfer) is displayed when a user sends an e-mail message via the private server, so long as the user has first activated the Configure Program icon  12   j  in the Program Area  10 . A user configures a software program of the present invention by supplying the required information requested. 
     An Encrypting Window  80  conveys to the user that the file(s) being sent are being encrypted but the processes of encryption and decryption are actually transparent to the user, once configuration of a software program of the present invention has been completed. The user therefore does not need to learn the encryption software or maintain encryption keys. 
     In one embodiment, messages between the client and server are transmitted in a format in which message encryption is accomplished with file compression software. Therefore when a message is encrypted it&#39;s also compressed because the encryption algorithm compresses data. Examples of encryption software includes PkZip 2.04G sold by PkWare, and other PKZip compatible software. If a message is from one user of the program to another, then nothing else is done as far as encryption is concerned and the encrypted file is transferred, in encrypted form by the server from the sending client to the receiving client. If a message is from a program user to an internet address, then the server converts it to the standard RFC-822 format. MIME/Base64 encoding is used for non-textual data in one embodiment of the invention. Messages received from the Internet for program users are routed to the users without change, except for the transport envelope between the server host and the client. In this embodiment, the program uses two protocols for communication between server and client software; Secure HTTP (https) and a customized protocol. 
     Accessing Stored Files 
     The present invention also allows a user to access all the different kinds of application files stored into a user-defined, activity-oriented folder in the ARCHIVE folder  42 . With continuing reference to  FIGS. 6 to 10 , a user may access documents and files created from different applications but stored within a single, user-defined activity-oriented folder with ease. For example, to access the stored files in Activity A folder  42   a , a user would open the ARCHIVE folder  42  and activate the Activity A folder  42   a , which appears as highlighted in the My Documents area  34 . Shown in the Workspace Area  90  are the individual files  44   a  to  44   p  ( FIG. 6 ) that are stored in Activity A folder  42   a . As discussed above, these files are different kind of objects created from different applications. 
     Address Book Functionality 
       FIG. 11  shows the functioning of a software method of the present invention when the Contacts Tab  54  is selected. When the Contacts Tab  54  is selected, an ADDRESS BOOK area  56  is displayed. The ADDRESS BOOK Area  56  corresponds to the My Documents area  34  when the Folders Tab  32  is selected. (Refer to the description of  FIG. 4 ). When the ADDRESS BOOK  56  is selected, the Workspace  90  displays a list of contacts that have been stored in ADDRESS BOOK  56 . A user enters the particulars of a contact by keying in the requested information in Fields  62 ,  64 , and  66 . A user may also create folders in the ADDRESS BOOK Area  56  in which related contacts may be stored. Shown in  FIG. 11  is Activity A folder  58 , which contains three contacts,  58   a - c.    
     With continuing cross reference between  FIG. 11  and  FIGS. 6 ,  8 - 10 , Contact  1 , identified as  58   a  in  FIG. 11 , is the same Contact  1  as listed in Field  70   f  of file  44   a . Contact  1  sent the Memo on Activity A file,  44   a , as shown in  FIGS. 6-10 . To send a document to a particular contact, a user, working with the Contacts Tab  54  activated, uses the pick-and-drop technique. The user picks a contact from those shown within the Workspace Area  90  (typically by clicking on it). For example, in  FIG. 11 , Contact  4 ,  58   c , may be selected. A user then activates the Folders tab  32 , opens the Activity A folder  58 , activates an activity-oriented folder, for example, Activity A  42   a , as shown in  FIGS. 6-10 . The user then “drops” the contact onto a file in Activity A  42   a  by deactivating the contact. The contact is now associated with the file and the file may now be sent to the contact. 
     Relationships Among Program Modules 
       FIG. 12  shows a state diagram that illustrates the collaboration and interactivity among modules and part modules especially as these relate to information input by a user of a software program of the present invention. The modules comprise Main Display  300 , File System Extension,  310 , Point-and-Click Interface  330 , Communication with Server  350 , Pick-and-Drop Interface  360  and Custom Dialogues  370 . The program modules allow user interaction with contacts, documents, web links, mail and other objects that are stored within and accessible from a user-defined activity folder. 
     Main Display  300  and File System Extension  310   
     The Main Display  300  represents the choices available to the user when the inventive program first opens: namely, the Folder Tree  302 , the Document, Contact or Tool List  304  or the Toolbar  306 . File System Extension  310  provides data to files shown in the Main Display  300 , which a user may access through the Folder Tree  302  of the Main Display  300 . Two-way communication exists between the Main Display  300  and File System Extension  304 , which means that the File System Extension  304  allows a user to add various kinds of information to different kinds of file types and the information will be shown in the Main Display  300 . There are several pieces of information the File System Extension  310  allows a user to add to a file, including Address Information  312 , Extended Document Title  314 , Extended Date/Time Information  316 , Color Coding  318 , Document Sticker  320 , Contacts  322  and Contact Groups  324 . 
     The File System Extension  310  receives information input from the Main Display  300 , the Point-and-Click Interface  330 , Communication with Server  350 , the Pick-and-Drop Interface  360  and sends the information to the files and objects displayed in Main Display  300 . 
     Point-and-Click Interface  330   
     From the Main Display  300 , a user may activate a Point and Click Interface  330  to accomplish various operations. Activating a Point and Click Interface  330  may be done by using any device having a pointing function, such as a mouse, trackball, touchpad, etc. The operations that may be accomplished through a Point and Click Interface  330  include Folder Tree Navigation  332 , Document Browsing/Editing  334 , Document/Contact Color Coding  336 , Sticker Editing  338 , Address Filtering  340 , Toolbar Contacts  342 , External Programs  344 , New Document Creation  346  and program Tools  348 . 
     Through the Point-and-Click Interface  330  the user may interact with Custom Dialogues  370 , a Pick-and-Drop Interface  360  or Communication with Server  350 . The Point-and-Click Interface  330  receives information from the Main Display  300  and sends information to the Pick-and-Drop Interface  360 , Communication with Server  350  and the File System Extension  310 . 
     Communication with Server  350   
     A Communication with Server  350  module allows the user to perform various functions, including Sending and Receiving Mail  352 , Encryption and Decryption  354 , Security Protocol  356  and Confirmation Receipts  358 . Communication with Server  350  receives information from Point-and-Click Interface  330  or Pick-and-Drop Interface  360  and sends information to the File System Extension  310 . 
     Pick-and-Drop Interface  360   
     The Pick-and-Drop Interface  360  receives information from the Point-and-Click Interface  330  and sends information to Custom Dialogues  370 , Communication with Server  350  and File System Extension  310 . 
     Custom Dialogues  370   
     Various customized dialogues may be displayed to a user in response to information that is received from the Point-and-Click Interface  230  or Pick-and-Drop Interface  260  and then sent to the File System Extension  210  module. These dialogues include Contact Information  372 , Message  374 , Question  376 , Color Selection  378 , Document Title Input  380 , Sticker Input  382 , program Setup  384 , External Mail Configuration  386 , Encryption Setup  388 , New User Registration  390  and Password Input  392 . 
     Although the invention has been described with a certain degree of particularity, it should be recognized that elements thereof may be altered by persons skilled in the art without departing from the spirit and scope of the invention. One of the embodiments of the invention can be implemented as sets of instructions resident in the random access memory of one or more computer systems configured generally as described in  FIG. 1 . Until required by the computer system, the set of instructions may be stored in another computer-readable memory, for example, in a hard disk drive, or in a removable memory such as an optical disk for use in a CD-ROM drive or a floppy disk for eventual use in a floppy disk drive. Further, the set of instructions can be stored in the memory of another computer and transmitted over a local area network or a wide area network, such as the Internet, when desired by the user. One skilled in the art would appreciate that the physical storage of the sets of instructions physically changes the medium upon which it is stored electrically, magnetically, or chemically so that the medium carries computer-readable information. 
     Operation 
       FIG. 13  is a flow chart diagram showing the operation of a client program according to one aspect of the present invention. After program start  410  an initialize program sequence  411  is performed an a toolbar display  412  is presented. In addition, a “display folder tree” subroutine  413  is performed. A “display contents of current folder” subroutine  414  is performed and user input is monitored  415 . User input is processed by a “process user input” subroutine  416  and a determination  417  is made if the folder tree is changed. If the folder tree has changed the display folder tree subroutine  413  is again performed; if not a determination  418  is made of whether the folder contents have changed. If the folder contents have changed, the “display contents” subroutine  414  is again performed; if not, a determination  419  is made whether to exit program. If the program is not to be exited, the program continues to monitor user input  415 ; otherwise, a de-initialize program subroutine  420  is performed. After deinitialization  420 , the program terminates  421 . 
       FIGS. 14A-14C  are flow chart diagrams showing the operation of a “display contents of current folder” routine  414  used with the client program of  FIG. 13 . Upon start  431 , an extended file information set is read  432 . This provides file information stored in the folder. A temporary list of extended file information records is made  433 , and the first file in the folder is located  434 . A determination  435  is made if the first file in the folder is located  434 . If the first file in the folder is located  434 , then a display  436  of standard file information is made. Extended file information for this file is found  437 , a determination  438  is made of whether the extended file information is found and a determination  439  is made of whether an extended title is found. If these determinations  438 ,  439  result in “yes” answers, then a display  450  is made of an extended title. If these determinations  438 ,  439  result in a “no” answer, then no display  450  of the title is made. The non-determination is usually indicative of a hidden file or another file type which would typically not be used by someone working with the file system at a user level. In either case, a determination  451  is made as to whether a sticker note is found. If a sticker note is found, a display  452  of the sticker note is made regardless of whether the sticker note is found  451 , a decision  453  is made as to whether color coding is found. The color coding is a function of the software coded according to one embodiment of the invention and indicates a user preference for the file. If color coding is found ( 453 ), the color coding is displayed  454 . Regardless of whether the color coding is found ( 453 ), a determination  455  is made as to whether a communication record is found. If a communication record is found, a display  456  is made of the communication time, display  457  of the communication direction is made, a display of  458  of the communication address is made, and a deletion  459  is made of the extended file information from a temporary list. 
     Regardless of whether a communication record is found ( 455 ), a find  460  of the next file in the folder executed. At this point, the sequence beginning with the determination  435  is made of whether the file is found, and the sequence is continued. If the determination  435  of whether the file is found is negative, then a find  461  procedure is instituted to locate the first record in the temporary list. A determination  462  is made as to whether the record is found. If the record is not found, then the routine terminates  463 . If the record is found, a determination  464  is made as to whether the record is a communication record. If the record is a communication record, then a display  465  of communication time, a display  466  of communication direction and a display  467  of communication address made. If the determination ( 464 ) is that the record is not a communication record, then a determination  468  of whether the record is a contact record is made. If the record is a contact record, then the contact information is retrieved  469  from a contact list, and a display  470  is made of the contact information. If the record is determined ( 464 ) not to be a communication record, or a determination ( 468 ) is made that the record is not a contact record, or the display of communication or contact ( 465 ,  466 ,  467  or  470 ) is made, then the next record in the temporary list is found for  471 . The record found determination  462  is repeated until the last record in the temporary list is found. The records may be displayed as a communication address  467  or as a contact information display  470 . At that time, the result of the record found decision  462  is negative and the process terminates  463 . 
       FIGS. 15A-15C  are a flow chart depicting the processor user input step  416  of  FIG. 13 . The “process user input” subroutine accepts one of a number of different user inputs. In the example, user inputs  501 - 520  are processed. These include, create new document  501 , create new folder  502 , create new contact  503 , open document  504 , open contact  505 , rename  506 , copy document  507 , move document  508 , move folder  509 , duplicate document  510 , delete  511 , print document  512 , color code document  513 , sticker attach  514 , add to contacts  515 , send document  516 , send to  517 , reply  518 , cancel sending  519 , and connect to server  520 . Each of these user inputs  501 - 520  invokes a corresponding decision. Upon each decision, a corresponding procedure  531 - 550  is invoked. 
     Procedure  542  is used to invoke a print program which is supplied with the operating system, such as Microsoft Windows 9x or later editions. The “print document” procedure  542  is treated in a different manner than the other procedures  531 - 541  and  543 - 550  in that the “print document” procedure  542  executes through an external printing routine provided with the operating system or otherwise separately installed. The “print document” procedure  542  is executed by a separate program which is associated with the operating system, such as the Microsoft Windows Operating System. In order to provide an acknowledgment to the “process user input” subroutine  416 , the “process user input” subroutine  416  is not terminated  562  until the conclusion of the “print document” process  542 . Print routines such as the Microsoft Windows “print” function, Postscript, Ghostscript and others are well-known to those skilled in the art of consumer level computers. The use of these print routines avoids a requirement to configure printers for each installed program. In the case of the present invention, the use of standard print routines provides convenient printing capabilities which can be executed according to the configuration of the printer and a file registration list. 
     In addition, it is possible to provide for processing other requests  561 . After all decisions  509 - 520  and other process requests  561  are executed, the “process user input” subroutine  416  terminates  562 . 
     Each of  FIGS. 16-32  depict respective ones of the processes or procedures invoked by the “process user input subroutine  416 . 
       FIG. 16  is a flow chart depicting the “create” procedure  531 . Upon invoking the create procedure  531 , an empty document is created  601 , and the document is opened in a window  602 . The user is able to execute instructions, typically text input, and the process waits for the user to close  603  the document window. A determination  604  is made as to whether the document is modified, and if it has not been modified, the new occurrence of the document is deleted  605 . If the document has been modified, the user is prompted  606  for a document title. The document title is used to set  607  the document name. The user input is then ended  562 . 
       FIG. 17  is a flow chart depicting the “create new folder” routine  532 . Upon invoking the “create new folder” routine  532 , the user is prompted for a folder title  611  and a folder is created  612 . At that point, the waiting for user input routine ends  562 . 
       FIG. 18  is a flow chart depicting the “open contact” routine  535 . Upon invoking the open contact routine  535 , information is read  626  from a contact file. The contact information is displayed  621  in an information window. After displaying the contact information  621 , the process waits  622  for user input, and a determination  623  is made as to whether the contact information is modified. If the contact information is modified, the information is saved  624  to the contact file. In either case, the process terminates  562 . If the “new contact” routine  533  is invoked, the display  621  of the contact information is performed followed by waiting for user input  622  and determining if contact information is modified  623 . The modified information is then saved  624 . 
       FIGS. 19A and 19B  are a flow chart depicting the “open document” routine  534 . Upon invoking the “open document” routine  534 , a determination  631  is made as to whether the document is already open. If the document is already open, the process switches  632  to an “open document” window. If the document is not already opened, a determination  633  is made as to whether the document is unread. If the document is unread, the document is then marked  634  as read. Whether or not the document is marked as read or unread, a determination  635  is made as to whether the document is a contact file. If the document is a contact file, a determination  637  is made as to whether the document is already in the contact list. If the document is in the contact list, the process terminates  562 . If not, the document is added  638  to the contact list and the process terminates  562 . If the document is not a contact file, a determination  639  is made as to whether the document is an executable file. If the document is an executable file, the executable file is executed  640  and the process terminated. If the document is not an executable file, a determination  641  is made as to whether the document is a web link, and if so, the web link is opened  642 . If the document is not a web link, a determination  643  is made whether the document is protected from modification. If the document is protected from modification, a backup copy  644  is made and the document is nevertheless opened  645  in a window. The backup copy is used as the protection from modification. If the document is not protected from modification, the document is nevertheless opened  645  in the window, but the backup copy (block  644 ) is not made. After the document is opened  645 , the process waits  646  for the user to close the document window. A determination  647  is made as to whether the document is modified. If the document is modified, a determination  648  is made as to whether the document is protected. If the document is protected from modification, the modified document is renamed  649  and the original document  650  is restored from the backup copy. The process terminates when a determination that the document is not protected is made in block  648  or the original document is restored from the backup copy  650 . At this time, the process is terminated  562 . If the document has not been modified (block  647 ), a determination  651  is made as to whether the backup copy has been created  644  is made. If the backup copy is made, the backup copy is deleted  652  and the process terminated. If the backup copy has not been created, the process terminates  562  regardless. 
       FIG. 20  is a flow chart depicting the copy and move process  537 , shown in  FIG. 15 . After the copy/move process  537  is invoked from either the copy document determination or the move document determination  508 , a determination  661  is made as to whether the folder is considered to be deletable. If the folder is considered deletable, the delete process  541  is invoked. If the folder is not considered to be deletable, a determination  663  is made as to whether the document is already in a destination folder. If the document is not in the destination folder, a copy of the document is created  664  in the destination folder. If the document is already present in the destination folder, a determination  665  is made as to whether to move the folder. If the folder is to be moved, the document is deleted  666  from the current folder and the process terminated  562 . If the document is not to be moved, the process is terminated. 
       FIG. 21  is a flow chart depicting the “move folder” process  539  invoked by the “process user input” subroutine  416  of  FIGS. 13 and 15 . Upon initiation of the move folder routine  539 , a determination  671  is made as to whether the destination folder is a subfolder of the source. If the destination is a subfolder of the source, the process terminates. If the destination is not a subfolder of the source, the folder is moved  672  to the destination and the process terminates  562 . 
       FIG. 22  is a flow chart depicting the response to the “rename” process of  FIG. 15 . Upon invocation of the rename process  536 , the user is prompted  677  for a new name. The new name is then set  678  and the process terminated  562 . 
       FIG. 23  is a flow chart depicting the “duplicate” routine  540 . Upon invocation of the “duplicate” routine  540 , the user is prompted  681  for a new document title and a copy of the document with the new title is created  682 , and the process is terminated  562 . 
       FIG. 24  is a flow chart depicting the response to a delete call  541 . Upon invocation of the delete call  541 , a determination  691  is made as to whether the trash is the current folder. If the trash is the current folder, the folder is deleted  692  from the disk. If the trash is not the current folder, the trash is set  693  as the destination and a request move operation  694  is initiated. This invokes the copy/move call  537 . If the folder is deleted from the disk  692 , the process terminates  562 . 
       FIG. 25  is a flow chart depicting a response to a color call  543 . Upon invoking the color call  543 , a color picker window is displayed  701  and user input  702  is received. Upon receipt of user input  702 , the new color is assigned  703  to the document and the process terminated  562 . 
       FIG. 26  is a flow chart depicting the response to a sticker call  544 . Upon receipt of the sticker call  544 , the process displays  710  a sticker editor window. User input  711  is awaited and a determination  712  is made as to whether the sticker is empty. If the sticker is empty, the sticker note  713  is removed and the process terminated  562 . If the sticker is not empty, the sticker note is attached  714  to the file and the process terminated  562 . 
       FIG. 27  is a flow chart depicting the response to the add contacts call  545 . Upon invocation of the add contacts call  545 , a determination  721  is made as to whether the document has been sent. If the document is sent, the recipients on the document are added  722  to the contact list and the process terminated  562 . If the document has not been sent, a determination  723  is made as to whether the document has been received. If the document has been received, the sender is added  724  to the contact list and the process terminated. If the document has been neither sent nor received, the process is terminated  562 . 
       FIG. 28  is a flow chart depicting the response to the send call of  546 . Upon receipt of the send call  546 , a copy of the document is sent  731  to an outbox. A control record is also created  732  in the outbox and a communication record is created  733  in the current folder. The communication record is marked  734  as “unsent” and the process terminated  562 . 
       FIG. 29  is a flow chart depicting a system response to a send to call  547 . Upon invocation of the send to call  547 , a contact information window is displayed  741  and the process awaits user input  742 . A determination  743  is then made as to whether the contact information has been modified. If the contact information has not been modified, the process terminates  562 . If the contact information has been modified, a determination  744  is made whether to add the contact information to the contacts. If the information is to be added to the contacts, the information is saved  745  to the contact file and the recipient address is set  746 , followed by invoking a send operation  546 . If the contact information is not added to the contacts, the send operation  546  is also invoked. 
       FIG. 30  is a flow chart depicting the system response to a reply call  548 . Upon receipt of the reply call  548 , a determination  751  is made as to whether the document has been received. If not, then the process is terminated  562 . If the document has been received, a determination  752  is made as to whether the document is marked as “unread”. If the document is marked as “unread”, the document is marked  753  as “read” and an empty reply  754  is created. If the document is not marked as “unread”, the empty reply  754  is created. If creating the empty reply  754 , a header is inserted  755  into the reply and a determination  756  is made as to whether the document has a sticker. If the document has a sticker, the sticker is inserted  757  into the reply. After inserting the quoted sticker text into the reply  757  or a negative determination is made that the document has a sticker, a determination  758  is made as to whether the document is text. If the document is text, the quoted document text is inserted  759  into the reply and the reply is opened  771  in a window. If the document is not text (block  758 ), the reply is opened  771  in the window without the inserted quoted document text. After the window is opened  771 , user response is awaited  772  in order to close the reply window. A determination  773  is made as to whether a reply is modified. If the reply is modified, the subject line is set  774  and the recipient address is set  775 . This results in an invocation of the send call  546 . If the reply has not been modified (block  773 ), the reply is deleted  776 , and the process terminated  562 . 
       FIG. 31  is a flow chart depicting a response to a cancel send call  549 . Upon invocation of the cancel send call  549 , the document to be canceled is deleted  781  from the outbox, the control record is deleted  782  from the outbox and the communication record is deleted  783  from the current folder. The process is then terminated  562 . 
       FIG. 32  is a flow chart depicting a response to a connect call  550 . Upon invocation of the connect call, a determination  791  is made as to whether a connection is already in progress. If a connection is not in progress, a connection is initialized  792  and a connection  793  to the server is effected. Upon connection to the server, a determination  794  is made as to whether the connection has failed. If the connection has failed, the connection is de-initialized and process outbox changes and process inbox changes are made  796 ,  797 . The process is then terminated  562 . If the connection has not failed, files from the outbox server are sent  798  and files from the server are received  799  and placed in the inbox. The connection is then de-initialized  795 , outbox changes are processed and inbox changes are processed  796 ,  797 , followed by process termination  562 . 
       FIG. 33  is a flow chart showing the process of sending files from the outbox to the server  798  of  FIG. 32 . Upon starting  831  the send operation, a first control record is found  832  in the outbox. A determination  833  is made as to whether the record is found. If a record has not been found, the send operation  798  is ended  834 . If a record has been found, a request is made for the recipient&#39;s public key  835  and a determination  836  is made as to whether the public key is obtained. If the public key is obtained, the file is encrypted  837  with the public key, and the control record is sent  838  to the server. If the public key is not obtained, a determination  839  is made as to whether the recipient is marked “enforced encryption”. If the recipient is not marked with “enforced encryption”, the control record is sent  838  to the server. After sending the control record to the server in either case, the file is sent  840  to the server, the file is deleted  841  from the outbox, the control record is deleted  842  from the outbox and a find  843  operation is performed for the next control record. If the recipient is marked with “enforced encryption”, the find operation  843  is invoked but the file is not encrypted nor sent. After invoking the find operation  843 , the process then again determines  833  if the control record is found and the process continues until a control record is not found, thereby ending  834  the process. 
       FIG. 34  is a flow chart showing the operation of the “send files from outbox to server” routine  798  depicted in  FIG. 32 . Upon process start  851 , a find operation  852  is initiated to find a first communication record marked as “unsent”. A determination  853  is made as to whether the communication record is found. If the communication record is found, a determination  854  is made as to whether a corresponding file exists in the outbox. If a corresponding file is in the outbox, the communication is marked  855  as “sent”. Then a find next communication record marked as “unsent” is initiated. The next marked as “unsent” is also found if the corresponding file does not exist in the outbox (block  854 ) with marking the (nonexistent) corresponding file as sent. This initiates the determination  853  as to whether the communication record is found. If the communication record is not found, the process ends  857  and the “process inbox changes”  797  routine is initiated ( FIG. 32 ). 
       FIGS. 35A and 35B  are a flow chart showing the process for the processing of outbox changes  796  shown in  FIG. 32 . Upon start  861 , the process first attempts to find  862  a first control record in the inbox. A determination  863  is made as to whether the control record is found. If the control record is found, a determination  864  is made as to whether the message is an RFC-822 record. An RFC-822 record is typically received from outside sources on the Internet and is handled accordingly by processing  865  as an RFC-822 record. If a control record is not found (determination  863 ), the process  797  is ended  866 . If the message is found but is not an RFC-822 message (determination  864 ), a determination  867  is made as to whether the message is encrypted. If the message is encrypted, the message is decrypted  868  with the user&#39;s private key. In either case, extended information is read  869  from the control record. A determination  870  is then made as to whether the message is a delivery confirmation receipt. If the message is a delivery confirmation receipt, the original message is found  871 , and a determination  873  is made as to whether the original message is found. If the original message is found, the delivery time is added  874  to the document&#39;s extended information. If the message is not a confirmation receipt, then the new message contents are saved  877  as a new document, extended information is saved  878  with the new document and the document is marked  879  as “unread”. In the case of both receipted documents and new documents, the incoming message is deleted  875  from the inbox and the next control record is searched for  876 . This returns the process to the control record found determination  863  until no control record is found, resulting in process termination  866 . 
       FIGS. 36A and 36B  are a flow chart showing the processing of an RFC-822 message depicted in box  865  of  FIG. 35A . After start  881 , the message header is read  882  and a determination  883  is made as to whether the message is a multipart message. In the case of multipart messages, the message may be a “multipart-alternative” message or a “multipart-related” message. A determination  885  is made as to whether the message is a “multipart-alternative” message. If the message is a “multipart-alternative” message, all message parts except for the last part are deleted in  886 . If the message is not a “multipart-alternative”, a determination  887  is made as to whether the message is a “multipart-related” message. If the message is a “multipart-related” message, all message parts but the first are deleted  888 . In any of the above cases (decision  883 , decision  885  and decision  887 ), one message part is read  889  and presented to the user. In any case involving a non-multipart message (decision  883 ), or a “multipart-alternative” or “multipart-related” message, the remaining message parts are deleted (blocks  886 ,  888 ) and the remaining message part has been read  889 . At this point, a decision  890  is made as to whether a message part is found. If a message part is found, the message part is processed  891  and a next message part is found  892 . The determination  890  is again made as to whether the message part is found until all message parts have been processed. When the message part is not found (determination  890 ), a determination  893  is made as to whether 2 or more messages are in the inbox. If there are 2 or more messages in the inbox, a determination  894  is made as to whether the first resulting message is text. If the first resulting message is text, the contents of the first resulting message  895  are added as a sticker to all the other resulting messages and the first resulting message is deleted  896  from the inbox. This is a change in the RFC-822 packet in that the contents of the first resulting message has a text message or added as a sticker in step  895 . 
       FIG. 37  is a flow chart depicting the processing of the message part shown in block  891  of  FIG. 36A . Upon start  901 , a determination  902  is made as to whether the part is an encapsulated RFC-822 message. If the part is encapsulated RFC-822 message, the message is processed as an RFC-822 message, as depicted in block  865  and described in connection with  FIGS. 36A and 36B . This is often the case, wherein an entirely encapsulated RFC-822 message is forwarded by another email client. 
     If the part is not an encapsulated RFC-822 message, as determined at determination  902 , then the series of determinations  905 ,  906 ,  907  are made as to whether the message is “Base64”, “UUencoded” or “quoted-printable” encoded. The parts are then decoded  908 ,  909 ,  910  accordingly. 
     While the above provides a full and complete disclosure of the exemplary embodiments of this invention, equivalents may be employed without departing from the true spirit and scope of the invention. Therefore, the above description and illustrations should not be construed as limiting the scope of the invention which is defined by the appended claims.
