     DETAILED DESCRIPTION 
     Hereinafter, an exemplary embodiment of the present disclosure will be described with reference to the drawings. 
       FIG. 1  illustrates the entire configuration view of an information processing apparatus in the exemplary embodiment. The information processing apparatus includes a ROM  10 , a RAM  12 , a communication interface (I/F)  14 , a control device  16 , an input device  18 , a display device  20 , and a storage device  22 . 
     The control device  16  is configured with one or plural processors, retrieves a processing program stored in a program memory, such as the ROM  10 , and executes various processing by executing the processing program using the RAM  12  as a working memory. Some of the functions of the control device  16  may be implemented not by software processing by program execution but by hardware processing. The hardware processing may be performed using a circuit, such as an ASIC or a field programmable gate array (FPGA). When the control device  16  receives a user operation via the input device  18 , such as a mouse or a keyboard, the control device  16  retrieves a file, such as a document stored in the storage device  22 , and displays the file on the display device  20 . The storage device  22  is configured with a hard disk drive (HDD), a solid state drive (SSD), or the like, and includes plural repositories as plural storage regions. In the drawings, plural repositories are illustrated as plural folders  24 ,  26 , and  28 , and each folder stores files, such as one or plural documents. 
     The control device  16  includes an operation receiving module, a display control module, and a storage control module as functional modules in order to execute each process. Here, “module” refers to a logically separatable component such as software and hardware. The modules may correspond to functions in a one to one correspondence relationship. Alternatively, one module may be implemented by one program. Further alternatively, plural modules may be implemented by one program. In addition, plural modules may be executed by one processor or by plural processors in a dispersed or parallel environment. In processing by each module, target information is read and processed by a processor, such as the CPU, and then the processing result is output. 
     The operation receiving module receives a user operation input from the input device  18  and supplies the user operation to the display control module. The user operation is an instruction to display a file, such as a document stored in the plural folders  24 ,  26 , and  28  of the storage device  22 , an instruction to move a file, such as a document, an instruction to edit, an instruction to delete, or the like. 
     The display control module functions as a first display controller to a third display controller, and displays file information, such as documents stored in the folders  24 ,  26 , and  28  in accordance with the received user operation. The display control module displays file information, such as documents stored in each of the folders  24 ,  26  and  28  on one common screen, and displays a storage region display that indicates in which folder each file, such as a document, is stored, on the common screen. Further, the common screen here is a display region that allows editing operations, such as file movement, for files stored in different folders (or different repositories) without depending on the stored folders. In addition, displaying the storage region display on the common screen may refer to displaying on the common screen such that the folder to which the file belongs can be identified. 
     The display form of the storage region display is any form, and any shape, pattern, or color or a combination thereof is used. The display forms can be changed from one another to identify the storage regions from one another. For example, file information of plural documents or the like stored in the same folder may be surrounded by closed curves of the same type, or colors of file information of plural documents or the like stored in the same folder may be standardized. The file information is, for example, a symbolic figure of a file, and specifically, an icon, a thumbnail or the like. The display control module displays the symbolic figures of the respective files on the common screen while maintaining a state where the respective files are stored in the folders  24 ,  26 , and  28 . In the following description, a closed curve that surrounds symbolic figures of files, such as documents stored in the same folder will be exemplified as the storage region display, and this will be referred to as the same group. The display control module moves and displays the symbolic figure of the file, such as the document, in accordance with the movement operation in a case where the symbolic figure of the file, such as the document displayed on the common screen, is moved and operated, and the storage region display is also changed in accordance with the movement of the symbolic figure. Specifically, the change in storage region display is, for example, the size change or deletion of the storage region display before and after the movement. 
     The storage control module functions as a controller, accesses the folders  24 ,  26 , and  28  of the storage device  22  and controls the storage of files, such as actual documents, in the folders  24 ,  26 , and  28 . The storage control module does not move the storage region in which the file, such as the actual document, is stored when moving the symbolic figure of the file, such as the document, in accordance with the movement operation by the display control module, and moves the storage region in which the file, such as the actual document, is stored at a specific timing. In other words, the storage control module reflects the movement of the file, such as the actual document, in the storage region at a specific timing after the movement operation. Before the specific timing, the symbolic figure of the file, such as the document, moves in accordance with the movement operation on the common screen, but the file in the storage region is not moved, and in a case where the specific timing is reached and the display control module is reflected in the storage region, the movement of the symbolic figure of the file on the common screen matches the movement of the file between the storage regions. The specific timing is the timing when the operation is completed, and the completion timing is determined by an explicit operation from the user, for example. The storage control module does not move the storage region of the file, such as the actual document, until the explicit operation from the user is received by the operation receiving module, and moves the storage region of the file, such as the actual document, in a case where the explicit operation from the user is received. 
       FIG. 2  illustrates a process flowchart of the exemplary embodiment.  FIG. 2  is a process flowchart of the control device  16 . 
     First, the control device  16  displays thumbnails of the files in the same repository as the same group on the common screen of the display device  20  (S 101 ). More specifically, in a case where there are plural repositories, the files stored in each repository of the plural repositories are collectively displayed on one screen such that the repository to which the file belongs can be identified. Specifically, the same repository is the same folder and is displayed as the same group. In a case where the folders  24 ,  26 , and  28  exist as plural folders as illustrated in  FIG. 1 , the files in the folder  24  are files in the same repository, the files in the folder  26  are files in another same repository, and the files in the folder  28  are files in yet another same repository. Therefore, the files in the folder  24 , the files in the folder  26 , and the files in the folder  28  are displayed as the same group. The thumbnails are reduced images as the symbolic figures of the files, and the sizes thereof do not matter. In a case where there are plural files in the same repository, the thumbnails that represent each file may further be reduced to have a smaller size than the standard size and displayed. The group display displays all the files in the same repository in a surrounding manner. 
     Next, the control device  16  determines whether a thumbnail movement operation has been received from the input device  18  (S 102 ). In a case where the movement operation is not received (NO in S 102 ), the process of S 101  is maintained. In addition, the control device  16  holds the group on the common screen in the memory, such as the RAM  12 , at a constant control timing. The held group can be used as a group before the movement operation which will be described later. In a case where the user operates the mouse or the like to move and operate one of the plural thumbnails displayed on the common screen (YES in S 102 ), the control device  16  determines whether the group exists at the coordinates on the common screen of the movement destination of the thumbnails (S 103 ). The determination is executed based on whether the coordinates of the thumbnail after the movement exist within the coordinate range that defines the group. Assuming that the coordinates on the common screen are defined by two-dimensional coordinates (x, y), when the coordinate range that defines a certain group is x1≤x≤x2 and y1≤y≤y2, in a case where the coordinates (xs, ys) of the thumbnail after the movement satisfy x1≤xs≤x2 and y1≤ys≤y2, it is determined that the group exists at the coordinates on the common screen of the movement destination of the thumbnail. 
     In a case where a group exists at the coordinates on the common screen of the movement destination of the thumbnail (YES in S 103 ), the control device  16  moves the thumbnail to the inside of the group of the movement destination and displays the thumbnail (S 104 ). On the other hand, in a case where a group does not exist at the coordinates on the common screen of the movement destination of the thumbnail (NO in S 103 ), the control device  16  creates a new group that includes the coordinates on the common screen of the movement destination of the thumbnail (S 105 ). 
     After moving the thumbnails to the group of the movement destination or creating a new group, the control device  16  changes and redisplays the groups of the movement source and movement destination (S 106 ). Specifically, for the group of the movement source, the group is reduced and redisplayed so as to include all the thumbnails after the thumbnails have moved. In addition, for the group of the movement destination, the group is enlarged and redisplayed so as to include all the thumbnails including the newly added thumbnail. In a case of creating a new group, the group is not enlarged or reduced, but when the occupied area of the group of the coordinates before the movement is 0, it can be said that the part from 0 to a limited occupied area is enlarged and redisplayed. 
     After the group is redisplayed, the control device  16  determines whether a restoration operation to the state before the operation has been received from the input device  18  (S 107 ). In a case where the restoration operation is received (YES in S 107 ), the control device  16  retrieves the group before the movement operation held in the memory, such as the RAM  12 , and displays the group on the common screen (S 110 ). In addition, in a case where the restoration operation has not been received (NO in S 107 ), it is further determined whether the reflection operation has been received from the input device  18  in the repository (S 108 ). In a case where there is no restoration operation to the state before the operation and there is no reflection operation in the repository (NO in both S 107  and S 108 ), the processing after S 106  is repeated. In a case where the reflection operation in the repository is received from the input device  18  (YES in S 108 ), the control device  16  reflects the thumbnail movement operation in the repository (S 109 ). In other words, although the control device  16  moves the thumbnail on the common screen of the display device  20  and changes the group in the processing of S 104 , S 105 , and S 106 , the files, such as the document stored in the folders  24 ,  26 , and  28  are maintained as it is, and in a case where the explicit operation of “reflect in repository” from the user is received, the control device  16  moves the files, such as the documents stored in the folders  24 ,  26 , and  28  so as to match the display of the thumbnail and the group on the common screen of the display device  20 . 
     Here, although it is also possible to move the actual file between the folders each time the thumbnail of the file is moved, since communication processing between the control device  16  and the storage device  22  occurs, it takes a corresponding amount of time. Meanwhile, the number of times of communication processing (the number of times of access to the storage device  22 ) between the control device  16  and the storage device  22  is reduced by moving the actual file between folders at a specific timing after the thumbnail movement operation. 
       FIG. 3  illustrates a detailed flowchart of S 106  in  FIG. 2 . 
     The control device  16  determines whether there is a thumbnail for the groups of the movement source and movement destination of the thumbnail (S 201 ). 
     In a case where there is a thumbnail (YES in S 201 ), the group is enlarged or reduced and redisplayed so as to include all the thumbnails (S 202 ). In other words, since the number of thumbnails decreases in the group of the movement source, the group is reduced and redisplayed, and since the number of thumbnails increases in the group of movement destination, the group is enlarged and redisplayed. When redisplaying the group, the shapes, colors, patterns, and the like of closed curves of the group before enlargement and reduction and the group after enlargement and reduction may be changed. The group before enlargement and reduction is displayed in gray and the group after enlargement and reduction is displayed in black, the group before enlargement and reduction is displayed in broken line, and the group after enlargement and reduction is displayed in solid line. The change between the group before enlargement and reduction and the group after enlargement and reduction may be displayed by animation. 
     In a case where there is no thumbnail (NO in S 201 ), the group is deleted from the display (S 203 ). When deleting the group, the group before deletion may be faded out and deleted. 
     Next, the common screen displayed on the display device  20  in the present exemplary embodiment will be specifically described. 
       FIG. 4  illustrates an example of a common screen displayed on the display device  20 . Thumbnails of the file group stored in the folder  24 , the file group stored in the folder  26 , and the file group stored in the folder  28  are displayed as symbolic figures on one screen, and the group is displayed surrounded by a closed curve as a storage region display for each folder. 
     The file groups stored in the folder  24  are displayed as thumbnails  24   a  to  24   f,  and a group  240  is displayed so as to include the thumbnails  24   a  to  24   f.    
     In addition, the file groups stored in the folder  26  are displayed as the thumbnails  26   a  and  26   b,  and a group  260  is displayed so as to include the thumbnails  26   a  and  26   b.    
     Furthermore, the file groups stored in the folder  28  are displayed as thumbnails  28   a  to  28   c,  and a group  280  is displayed so as to include the thumbnails  28   a  to  28   c.    
     All of the groups  240 ,  260 , and  280  are displayed in an elliptical shape, but may be in a circular shape or the like. In addition, the display form of the groups  240 ,  260 , and  280 , for example, the shape may be different for each group. For example, the group  240  may be elliptical, the group  260  may be circular, and the group  280  may be rectangular. The colors of the groups  240 ,  260 , and  280  may be different for each group. 
     The groups  240 ,  260 , and  280  are displayed at different coordinates on the common screen. Accordingly, the user can easily visually recognize that the thumbnails  24   a  to  24   f,  the thumbnails  26   a  and  26   b,  and the thumbnails  28   a  to  28   c  are stored in different folders, that is, different repositories. 
       FIG. 5  illustrates how the user moves the thumbnail by operating the input device  18 , such as a mouse. The thumbnail  24   a  in the group  240  is moved to the region where the group  260  exists. The control device  16  detects the movement of the thumbnail  24   a,  and compares the coordinates of the movement destination with the region coordinates of the group  260  to determine that the group  260  exists at the coordinates of the movement destination. 
       FIG. 6  illustrates a redisplay screen of the group  240  which is the group of the movement source of the thumbnail  24   a  and the group  260  which is the group of the movement destination of the thumbnails  24   a.  Since the number of thumbnails of the group  240  of the movement source is reduced by the amount of movement of the thumbnail  24   a,  the group  240  is reduced and displayed as a group  241 . On the other hand, since the number of thumbnails of the group  260  of the movement destination is increased by the added amount of the thumbnail  24   a,  the group  260  is enlarged and displayed as a group  261 . In addition, in the drawing, since the thumbnail  24   a  is grouped into the group  261  of the movement destination, reference numeral  24   a  is changed to reference numeral  26   c.  As for the group  280 , the group  280  is maintained as it is because there is no movement of the thumbnail. 
     In the lower portion of the common screen of  FIG. 6 , a button  300  for restoring to the state before the operation and a common screen  302  before the operation are displayed, and a button  304  for reflecting in the repository is displayed. The control device  16  holds the common screen (the screen illustrated in  FIG. 4 ) before the thumbnail movement operation in the memory, and inserts the common screen before the movement operation into the common screen and displays the common screen when displaying the common screen after the movement operation illustrated  FIG. 6 . The user can easily confirm the common screen before the movement operation by visually recognizing the screen  302 , and can redisplay the common screen before the movement operation by operating the button  300  as necessary. The change of the screen display by the operation of the buttons  300  and  304  will be further described later. 
       FIG. 7  illustrates how the thumbnail  24   a  is moved to a position other than the region where the groups  240 ,  260 , and  280  exist. The control device  16  determines that there is no group at the coordinates of the movement destination of the thumbnail  24   a,  and newly creates a group at the coordinates of the movement destination. 
       FIG. 8  illustrates a redisplay screen of the group  240  which is the group of the movement source of the thumbnail  24   a  and the group of the movement destination of the thumbnails  24   a.  Since the number of thumbnails of the group  240  of the movement source is reduced by the amount of movement of the thumbnail  24   a,  the group  240  is reduced and displayed as a group  241 . On the other hand, a new group  250  is generated at the movement destination of the thumbnail  24   a.  Since the new group  250  may include the thumbnail  24   a,  the size thereof may be smaller than that of the group  241 , for example. Since the thumbnail  24   a  is grouped into the group  250  of the movement destination, reference numeral  25   a  is changed to reference numeral  24   a.  Since the group  250  is a newly added group, highlighting display or blinking display may be employed in order to emphasize the group  250 . 
       FIG. 9  illustrates a state where the user operates the input device  18  to further move the thumbnail  25   a  from the common screen display of  FIG. 8 . The user moves the thumbnail  25   a  from the group  250  to the group  280 . 
       FIG. 10  illustrates a redisplay screen of the group  250  which is the group of the movement source of the thumbnail  25   a  and the group  280  of the movement destination of the thumbnail  25   a.  The group  250  of the movement source is deleted because the thumbnails no longer exist due to the movement of the thumbnail  25   a.  At this time, a state where the group  250  is deleted may be expressed by fade-out display. On the other hand, the group  280  which is the movement destination of the thumbnail  25   a  is enlarged and displayed in a group  281  because the number of thumbnails increases. 
       FIG. 11  illustrates a state where the user operates the input device  18  to further move the thumbnail  25   a  from the common screen display of  FIG. 8 . The user moves the thumbnail  25   a  from the group  250  to the vicinity of the group  241  which is a source group. Here, the term “vicinity” refers to “within a certain coordinate range from the group  241 ” and is set in advance as a processing program parameter. 
       FIG. 12  illustrates a redisplay screen of the group  250  which is the group of the movement source of the thumbnail  25   a  and the group  241  of the movement destination of the thumbnails  25   a.  When the control device  16  detects that the movement destination coordinates of the thumbnail  25   a  are in the vicinity of the group  241  of the source, the control device  16  regards this as the restoration operation to the group  241  of the source and returns the group  241  to the group  240  of the source. The group  240  of the source is a group including the thumbnail  25   a,  and the thumbnail  25   a  is restored to the thumbnail  24   a.  The group  250  of the movement source is deleted because the thumbnails no longer exist due to the movement of the thumbnail  25   a.  In other words, the group  250  is integrated into the group  241 . 
       FIG. 13  illustrates how the user operates the input device  18  to operate the button  300  on the common screen illustrated in  FIG. 6 . In addition, the common screen of  FIG. 6  is a screen in a case where the user moves the thumbnail  24   a  in the group  240  to the group  260 . 
       FIG. 14  illustrates the common screen after the button  300  is operated. In response to the operation of the button  300 , the control device  16  displays the common screen before the movement operation held in the memory. The screen is the same as the common screen of  FIG. 5 . In the related art, the “UNDO” function for restoring to the state before the operation is known. However, in the exemplary embodiment, the user can return to the common screen before the movement operation while confirming the common screen before the movement operation on the screen  302 . In addition, in  FIG. 14 , the button  300 , the screen  302 , and the button  304  are not displayed. This is because it is not necessary to display the buttons  300  and  304  and the screen  302  anymore because the screen has returned to the common screen before the movement operation. 
       FIG. 15  illustrates how the user operates the input device  18  to operate the button  304  on the common screen illustrated in  FIG. 6 . The user instructs the completion of the movement operation, and operates the button  304  in a case of moving an actual file. 
       FIG. 16  schematically illustrates the process of the control device  16  in a case where the operation of the button  204  is received. The control device  16  moves the files stored in the folders  24 ,  26 , and  28  in accordance with the thumbnail group grouped in the groups  241 ,  261 , and  280 . Since the group  241  corresponds to the folder  24  and the thumbnail  24   a  is moved, the file that corresponds to the thumbnail  24   a  is deleted from the folder  24 . In addition, since the group  261  corresponds to the folder  26  and the thumbnail  24   a  is added and becomes the thumbnail  26   c,  the file that corresponds to the thumbnail  24   a  is added to the folder  26 . Since the group  280  has not changed, the file in the folder  28  is maintained as it is. 
     The files stored in the folders  24 ,  26 , and  28  before and after the repository reflection will be described in more detail. 
     In  FIG. 15 , on the common screen, since the thumbnails  24   b  to  24   f  are grouped into the group  241  and the thumbnails  26   a  to  26   c  are grouped into the group  261 , the files that correspond to the thumbnails  24   b  to  24   f  appear to be stored in the folder  24  and the files that correspond to the thumbnails  26   a  to  26   c  appear to be stored in the folder  26 , but in reality, the files that correspond to the thumbnails  24   a  to  24   f  are stored in the folder  24 , and the files that correspond to the thumbnails  26   a  and  26   b  are stored in the folder  26 . Therefore, the group of the common screen and the actual storage situation of the folders  24  and  26  do not match. 
     On the other hand, on the screen of  FIG. 16 , as a result of reflection of the group on the common screen in the repository, the files that correspond to the thumbnails  24   b  to  24   f  are stored in the folder  24  and the files that correspond to the thumbnails  26   a  to  26   c  are stored in the folder  26 . Therefore, the group of the common screen and the actual storage situation of the folders  24 ,  26 , and  28  match each other. 
     In addition, in a case where the reflection in a repository is completed, the control device  16  may display the message having the contents on the common screen. In addition, the display of the group before reflection in the repository and the display of the group after reflection in the repository may be changed. For example, the display color of the group before reflection in the repository and the display color of the group after reflection in the repository may be changed. 
     Although the exemplary embodiments of the present disclosure have been described above, the present disclosure is not limited to the exemplary embodiments, and various modifications are possible. The modification examples will be described hereinafter. 
     MODIFICATION EXAMPLE 1 
     In the exemplary embodiment, in a case where there is a group at the coordinates of the movement destination of the thumbnail, the group is enlarged and redisplayed so as to include the thumbnail of the movement destination, but in a case where two files are combined as one file and have a bundling function, the function may be displayed on the common screen. 
       FIGS. 17 and 18  illustrate examples of the common screens in this case.  FIG. 17  illustrates how the user has moved the thumbnail  24   a  to the position of the thumbnail  26   b  in the group  260  by moving the thumbnail  24   a.  In a case where the coordinates of the thumbnail  24   a  of the movement destination and the coordinates of the existing thumbnail  26   b  overlap each other, the control device  16  considers this as a bundling operation to combine the two files. 
       FIG. 18  illustrates the redisplay screen of the group  240  of the movement source and the group  260  of the movement destination. Since the number of thumbnails of the group  240  of the movement source is reduced by the amount of movement of the thumbnail  24   a,  the group  240  is reduced and displayed as a group  241 . On the other hand, since the group  260  of the movement destination is a process of combining and bundling the files to which the thumbnail  24   a  is added, the thumbnail  24   a  is displayed superimposed on the thumbnail  26   b  as the thumbnail  26   c,  and the group  260  is not enlarged and displayed and maintains the same size as the group  260  of the source. 
       FIGS. 19 and 20  are operations reverse to those of  FIGS. 17 and 18 , and illustrate how to perform separating operation for separating two files combined (that is, bundled) into one file into two independent files of the source. When the user operates, for example, a menu to select separation of the files, the thumbnails displayed superimposed as illustrated in  FIG. 19  are separated into the thumbnail  26   b  and thumbnail  26   c.    
       FIG. 20  illustrates the redisplay screen of the group after the separation. Since the two thumbnails  26   b  and  26   c  are separated, the group  261  is enlarged and displayed in the group  262  so as to include the thumbnails  26   b  and  26   c.    
     MODIFICATION EXAMPLE 2 
     The exemplary embodiment exemplifies a case where the control device  16 , the input device  18 , the display device  20 , and the storage device  22  are incorporated in one information processing apparatus as illustrated in  FIG. 1 , but may be implemented by a server client system that sends and receives data via a communication network. Specifically, plural user terminals and a shared server may be connected via a communication network, the control device  16  of the user terminal may access the storage device  22  of the shared server, and a common screen may be displayed on the display device  20  of the user terminal.
