Description:
RELATED APPLICATIONS 
       [0001]    The present application is a divisional of U.S. patent application Ser. No. 10/021,494, filed Oct. 30, 2001, entitled “CATEGORY BASED USER INTERFACE FOR MANAGEMENT OF AUXILIARY STORAGE FOR A PORTABLE COMPUTER SYSTEM,” naming Jesse Donaldson and David Creemer as inventors, assigned to the assignee of the present invention, and having attorney docket number PALM-3674.SG. This application is incorporated herein by reference in its entirety and for all purposes. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    As the continuing advances in technology have enabled the further miniaturization of the components required in building computer systems, new categories of portable electronic devices and computer systems have been created. One of the newer categories of computer systems developed has been the portable, hand held, or “palmtop” computer system, commonly referred to as a personal digital assistant or PDA. Other examples of a palmtop computer system include electronic address books, electronic day planners, electronic schedulers and the like. 
         [0003]    A palmtop computer system is a computer that is small enough to be held in the user&#39;s hand and as such is “palm-sized.” As a result, palmtops are readily carried about in the user&#39;s briefcase, purse, and in some instances, in the user&#39;s pocket. By virtue of its size, the palmtop computer, being inherently lightweight, is therefore exceptionally portable and convenient. 
         [0004]    To support the diminutive form of the palmtop computer, certain components and functions normally associated with full-sized computers have been reduced or redesigned to facilitate portable use. To conform with the size limitations of the palmtop computer, the hard drive, the component normally utilized for data storage, has been generally replaced with quantities of RAM (random access memory), ROM (read only memory), and with removable memory, e.g., flash memory, etc. 
         [0005]    Conforming to the size of the palmtop computer, new types of media cards have been developed for the PDA. These new media cards are called auxiliary add-in cards, or are also called secure digital, SD cards, Compact Flash (CF), or multimedia cards or MMCs, or memory sticks. These media cards are inserted into the PDA through an accessible expansion slot thereby providing a mechanism to add functions to a PDA while continuing to conform to the size restrictions of the PDA. The advantage of having an expansion slot is the ability to use the auxiliary add-in cards for providing the PDA with an almost endless array of different information and applications. SD and MMC add-in cards, by virtue of their size, (at approximately 32 mm long by 24 mm wide by 2.4 mm thick, are just slightly larger than a postage stamp) are easily carried by the user, and are also convenient to use. 
         [0006]    Many users are familiar with the “copy” and “paste” functions used on a desktop computer to copy and move files from one place to another. For example, on a desktop computer, one can copy a file from a floppy disk and paste it onto the hard drive of the computer to make an identical copy of the file. The actual mechanism that facilitates the copy function can be a “drag and drop” function using a graphical user interface. However, many file structures used on a palmtop computer do not incorporate a “desktop analogous” method for managing data between the main memory on the palmtop device and a removable memory card associated with the palmtop device. 
       SUMMARY OF THE INVENTION 
       [0007]    To appreciate the convenience of using expansion cards on a portable electronic device, a user friendly method of file sharing is presented. It would be advantageous to create a file structure on a palmtop computer that is easily recognizable to the user and requires little training to learn and that can be used to copy information between a main memory of a palmtop device and a removable memory card. 
         [0008]    Accordingly, embodiments of the present invention provide a file structure for use with removable memory (expansion cards) that is operable with some existing functions existing already on a palmtop computer. The present invention further provides a method for sharing information on an expansion card with a palmtop computer. More specifically, an embodiment of the present invention provides a method for filing the information on an expansion card as a category of the palmtop computer. 
         [0009]    In embodiments of the present invention, the files of an expansion card can be assigned to a special category or categories that are associated with external memory storage. In one implementation, applications that are on a PDA can be copied to a removable storage unit by changing the category the applications are assigned. For example, a game that is stored on the main memory of a PDA (category “games”) can be copied to a removable memory card by simply changing the category the game is in to indicate a predetermined category associated with the removable card (e.g., category “removable card”). In one embodiment, the user has the option to keep the application in two categories. For example, after copying a game from the PDA to a removable memory card, the user can decide if the game will remain on the PDA or it will be removed therefrom. 
         [0010]    Likewise, an application that is resident on a memory card can be copied to the memory of the PDA by changing its category name to a category associated with the PDA, e.g., “games.” The present invention also provides a user interface that can be used to easily change the category of the application. In one implementation, categories that are associated with external memory cards have a special visual indication to denote the external memory storage. Additionally, icons that are related to applications within categories that are associated with external memory cards can also be displayed with a special visual indicator denoting the external storage thereof. 
         [0011]    These and other objects and advantages of the present invention will no doubt become obvious to those of ordinary skill in the art after having read the following detailed description of the preferred embodiments which are illustrated in the various drawing figures.

         [0039]    It is appreciated that computer system  100  described herein illustrates an exemplary configuration of an operational platform upon which embodiments of the present invention can be implemented. Nevertheless, other computer systems with differing configurations can also be used in place of computer system  100  within the scope of the present invention. 
         [0040]      FIG. 4  is an illustration of a Personal Digital Assistant (PDA)  100  that comprises a plurality of information files, e.g., applications, data, documents, configuration information, etc., hereinafter, “files.” The files may contain applications that are programs such as games, an address book, or calendar, etc. On PDA  100 , there is a drop-down menu  150  that comprises the different categories where files can be stored. Each file can be assigned to a category name. The user can create new category names, or amend existing names, in well known fashions. In accordance with the embodiments of the present invention, the user can define categories that relate only to storage on removable memory devices, e.g., expansion cards. Generally, by associating a file (stored in non-removable memory) with a category name of the removable memory, that file becomes copied to the removable memory. Vice-versa, by associating a file (stored in removable memory) with a category name of the non-removable memory, that file becomes copied to the non-removable memory. 
         [0041]    In this particular illustration of  FIG. 4 , drop-down menu  150  reads “All.” This selection will display information in all categories, e.g., icons of all of the files that are stored on PDA  100  including any information stored in the currently inserted expansion memory card  104  ( FIG. 3 ). In this example, only application files are stored. For example, application AP 1   151  is displayed as an icon on the PDA. AP 1   151  is an application that resides in one of the categories of drop-down menu  150 . Also shown are other applications represented as icons AP 2 -AP 6 . 
         [0042]      FIG. 5  is an illustration of PDA  100  having a plurality of applications that are stored in the category “card.” To display the files stored in the category “card,” the user selects the label “card” from the drop-down menu  150 . For descriptive purposes, “card” represents a category of files associated with the removable storage card. In one embodiment, once selected, only icons of the files stored in the “card” category will be displayed for easy user reference. In this embodiment, the category named “card” represents the removable storage unit  104  ( FIG. 3 ). As shown, applications  151 ,  155  and  153  are displayed on the computer screen  105  and relate to the files that are stored in the removable storage device  104 . 
         [0043]    In one embodiment, a removable storage card can have more than one category associated with the card. In another embodiment, the files stored on other removable storage cards (not inserted into the PDA) can be displayed upon the user selecting a category associated with those memories. However, the icons, in this case, will be displayed with visual attributes (such as being grayed out) to prevent the user form selecting those applications. 
         [0044]    By having the removable storage unit  104  represented by a category in the drop-down menu  150 , the present invention allows the user to use the category technique of storing data on PDA  100  to move data onto removable storage unit  104 . In one embodiment, icon  180  is displayed next to the application icon to remind the user that the application is on the removable storage unit  104 . For example, application AP 1   151  has icon  180  next to the lower right corner of the icon for AP 1   151 . Icon  180  signals the user that the application is stored on the removable storage unit  104 . Furthermore, category label  150  “card,” can be displayed with a special display attribute (or associated icon) indicating that this category includes information that is stored on the memory card. 
         [0045]      FIG. 6  is an illustration of a PDA  100  having a function that edits the category of a file (e.g., application) on system  100  and by doing so is able to automatically move or “copy” the data. Dialog window  160  shows the files that are stored on PDA  100 . Below the dialog box  160 , there are numerous options for manipulating the category in which an application resides. For example, if the user wanted to copy the application AP 4  from the main memory  102  to the removable storage unit  104 , the user would change the category of AP 4  from its current category e.g., “games,” to a new category associated with the removable card, e.g., “card.” To do this, an application can be selected, and the change category button  18  can be selected to bring up a new dialog box as described in  FIG. 7 . Alternatively, if a user wanted to “copy” an application from a removable storage card to the main memory of the PDA, the application would be selected, and the file&#39;s category can be changed from a category associated with the removable memory to a category associated with the main memory of the PDA. 
         [0046]    In one embodiment, an attribute is associated with file names and/or the category names in the various drop-down menus, e.g., menu  160  ( FIG. 6  or menu  150  of  FIG. 10 ) to indicate removable memory storage. For example, if an application in the drop-down menu resides on the removable memory card, a check mark  162  ( FIG. 6 ) can be placed next to the name associated with the application to remind the user that the application is stored on the removable memory card. Furthermore, with respect to an application in the drop-down menu that is stored on a removable storage card not coupled to the PDA, the name associated with the application can be grayed out or italicized so the user is not able to select the application and to alert the user that the application is stored on a non-inserted removable memory card. 
         [0047]    Regarding, category names,  FIG. 10  illustrates drop down menu  150 . Category “Card” has an icon  180   a  to indicate that this category is related to removable storage. Furthermore, a category  180   b  in the drop-down menu  150  that is related to information stored on a removable storage card that is not presently coupled to the PDA, is grayed out or italicized so the user is not able to select that category. In another embodiment, a category can be password protected to prevent unauthorized use. In another embodiment, a password protected category can also be grayed out to prevent the user from selecting a particular application. 
         [0048]      FIG. 7  is an illustration of a PDA  100  in the process of renaming a file&#39;s category. Notice dialog box  160  wherein the text notifies the user that the category that AP 4  is in is about to be changed to “card.” At this point in the process, the user would select the OK button  161  to affirm the change of category. In one embodiment, once the category of the file is changed to the removable memory, the file, e.g., application, is automatically copied from its original memory space to the removable memory card. The name “card” that is given to the category representing the removable memory  104  is only a genetic term used for descriptive purposes. The exact name of the category may be any name assigned to the card by the user or software used for embodiments of the present invention. 
         [0049]      FIG. 8  illustrates a process  800  that can be implemented as program code stored in computer readable memory units of a computer system and executed by the processor of the computer system. Although a variety of different computer systems can be used with the present invention, an exemplary Personal Digital Assistant computer system.  FIG. 8  is a process flow chart  800  that illustrates the process of copying a file, e.g., an application, from the main memory  102  or  103  on PDA  100  to removable memory  104  ( FIG. 3 ). Step  801  is to insert the memory card  104  into the PDA  100 . The next step  802  is to display a category of files where the category relates to information stored on memory  102  or memory  103 . Next, the user selects the application (of a category that includes information stored in memory  102  or memory  103 ) that is going to be copied to the removable memory card  104 . Once the application has been selected, the step  803  is to change the category to which the application is assigned to a category associated with the removable memory device. By changing the category of the application to “card,” the application will be automatically copied to the removable memory card  104 . 
         [0050]      FIG. 9  is an illustration of a PDA  100  comprising several files, e.g., applications, that are stored on the removable memory card  104  as a result of copying AP 4   154  to the removable memory card. Notice that drop-down menu  150  displays “card” as the selected category. Optional icon  180   b  is present to denote that the associated category relates to a removable storage device. The category named “card” comprises files AP 1   151 , AP 5   155 , AP 3   153  and AP 4   154 . The icons  180  that are next to the application icons are to remind the user that the applications are located on the removable memory  104  ( FIG. 3 ). Referring back to  FIG. 5 , notice that there are only 3 applications in the “card” category (AP 1   151 , AP 3   153 , and AP 5   155 ). Referring back to  FIG. 9 , notice that after changing the category of AP 4   154  to “card,” AP 4   154  is now included in the category called “card. 
         [0051]      FIG. 10  is an illustration of PDA  100  after changing the category in the drop-down menu  150  to “all.” Notice that the same six applications are displayed as in  FIG. 4 . However, icon  180  allows easy recognition of the files, e.g., applications, that are stored on the removable memory. For example, in  FIG. 10 , AP 1 , AP 3 , AP 4  and AP 5  have icon  180  next to them indicating that they are stored on the removable memory  104  ( FIG. 3 ). Also note in drop down window  150  that icon  180   a  is displayed next to the card label within window  150 . This also reminds the user that this category “card” relates to a removable memory. 
         [0052]      FIG. 11  is a flow chart  1100  that describes the process of copying a file, e.g., an application, from the removable memory  104  ( FIG. 3 ) to the main memory of the PDA  100 . The steps are analogous to the steps in process  800  ( FIG. 8 ) except the name of the category is changed from “card” to a category that resides on the main memory of the PDA  100 . For example, the first step  1101  of process  1100  is to insert the expansion card (removable memory  104  of  FIG. 3 ) into the PDA  100 . The next step  1102  is to display a category that includes information displayed in the inserted expansion card then choose the application that is to be copied from the PDA  100  to the removable memory  104 . Lastly, in step three  1103 , the category of the application is changed to the category that represents the expansion card  104 . 
         [0053]      FIG. 12  is a flow chart  1200  that represents an embodiment of the present invention that allows the user to keep a copy of a file in two different categories. For example, when an application is copied from the PDA  100  to an expansion card  104 , the user has the option to keep both copies or just move it form one category to another (e.g., eliminating the original copy). 
         [0054]    The first step  1201  of process  1200  is to insert the expansion card into the PDA. Next, the category list is updated to represent the card as a new category. In the category list, the card may be named “card” or it may be the name the user created for the card such as “games” or “address book.” The next step  1203  is to choose the application that is to be copied. Then the next step  1204  is to change the category of the application to the category that represents the removable memory card. Next in step  1205 , the application is copied from the main memory of the PDA to the expansion card. Once completed, in step  1206 , a dialog box will appear and ask the user if the application is to remain in the original category in addition to the expansion card. If the user answers “yes,” the process is complete. If the user answers “no,” in step  1207 , the application that was copied will be removed from the category it was in prior to being copied. 
         [0055]    If an application was to be copied from an expansion card to the PDA, the steps would be similar except the category would be changed from the category that represents the card to a category that is on the main memory of the PDA. The similar operation of copying files makes it very easy for the user to copy and move applications from removable memory to the PDA. 
         [0056]    In the foregoing specification, embodiments of the invention have been described with reference to numerous specific details that may vary from implementation to implementation. Thus, the sole and exclusive indicator of what is, and is intended by the applicant to be, the invention is the set of claims that issue from this application, in the specific form in which such claims issue, including any subsequent correction. Hence, no limitation, element, property, feature, advantage, or attribute that is not expressly recited in a claim should limit the scope of such claim in any way. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
