Description

  The present invention relates to an improvement of a file browsing apparatus, a file browsing control program, and a file browsing method used when browsing a file simply.

  A file browsing device used for simply browsing a file is known as a so-called viewer.

  The types of viewers already developed and marketed are specialized for text files, specialized for presentation files, specialized for image files, specialized for video files, etc. Yes.

  In general, this type of viewer does not depend on the creator (application program) that generated the file. For example, if it is a viewer for image files, the image can be used regardless of differences between manufacturers A, B, and C. It is configured so that the file can be browsed, and if it is a viewer for text files, the text file can be browsed regardless of differences in manufacturers such as D company, E company, and F company. The same applies to the viewer for presentation files and the viewer for video files.

  However, so far, there has not been provided a viewer configured to support all of text files, presentation files, image files, and video files.

  As a result, when there are multiple types of files in the same folder and you want to browse them all, the viewer selects the viewer to be activated according to each file type, and the startup procedure specific to the viewer is selected. It is necessary to start up a dedicated viewer by stepping on it. To view the next file of a different type, close the currently running viewer, the user selects the viewer to be started next, and the user re-selects the viewer. Therefore, it is necessary to repeat an operation such as starting up a dedicated viewer by following a startup procedure unique to the system, resulting in inconvenience that the operation required for browsing is troublesome.

  When the work memory capacity of the computer is sufficiently large, the image file viewer, video file viewer, text file viewer, and presentation file viewer are all started up. Although it is possible to make it resident in the memory itself, even in such a case, the selection operation and the browsing operation of each file must be performed using a window unique to each viewer. Still very annoying, the idea of launching various viewers together simply leads to a reduction in the startup time of a file browsing program that functions as a viewer.

  It seems that it is possible to build a viewer that can handle all of text files, presentation files, image files, and video files. However, in that case, it takes time and cost to research and develop the program. However, there is a problem that a single function type viewer such as a viewer for image files, a viewer for video files, a viewer for text files, a viewer for presentation files, which has been introduced so far, is wasted.

  For example, an image data generation apparatus and an image data generation method disclosed in Patent Document 1 are known as techniques that can handle a wide variety of types of files without depending on a program stored in a computer.

  However, the image data generation apparatus and the image data generation method are configured to import image data obtained by archiving an image reproduction program into a computer and reproduce the image data using the image reproduction program. Not too much.

  Naturally, this image playback program can be regarded as a kind of viewer, but even if such an apparatus or method is used to browse image files, video files, text files, and presentation files. As described above, there is no linkage between the viewer for image files, the viewer for video files, the viewer for text files, and the viewer for presentation files. Since the selection operation and browsing operation must be performed using a window unique to each viewer, the window switching operation is still troublesome.

JP-A-2005-341275

  An object of the present invention is to improve the above-mentioned inconveniences, to effectively use an existing file browsing program, and to continuously browse various types of files without performing complicated window switching operations. An object is to provide a file browsing apparatus, a file browsing control program, and a file browsing method.

The file browsing apparatus of the present invention achieves the above-described problem,
Program storage means for storing a plurality of file browsing programs specialized for the file type;
A selection operation detecting means for detecting a selection operation of a file to be browsed and displayed;

When the browsing program execution means detects the end of a file, and when the browsing program execution means receives a file type notification from the file type determination means while executing the file browsing program, the browsing And an execution program automatic ending means for automatically ending the file browsing program being executed by the program execution means.
Further, an automatic file selection means for automatically selecting a file to be browsed and displayed from a designated folder according to a predetermined order is provided, and the execution program automatic termination means is replaced with the file type notification. When the instruction to select the next file is detected, the file browsing program executed by the browsing program execution means may be automatically terminated.

The file browsing control program of the present invention achieves the same problem as described above,
A computer microprocessor having a program storage means for storing a plurality of file browsing programs specialized for a file type,
A selection operation detecting means for detecting a selection operation of a file to be browsed and displayed;
File type determination means for determining the file type of the file detected by the selection operation detection means;
A browsing program selection means for selecting a file browsing program corresponding to the file type determined by the file type determination means as an execution target;
Reading program execution means for reading and executing the file browsing program selected by the browsing program selection means, and
When the browsing program execution means detects the end of a file, and when the browsing program execution means receives a file type notification from the file type determination means while executing the file browsing program, the browsing The file browsing program being executed by the program executing means is configured to function as an execution program automatic ending means for automatically ending the file browsing program.
The microprocessor further functions as a file automatic selection means for automatically selecting a file to be browsed and displayed from a designated folder according to a predetermined order, and the execution program automatic termination means includes the file Instead of the type notification, when an instruction to select the next file is detected, the file browsing program executed by the browsing program executing means may be automatically terminated.

The file browsing method of the present invention achieves the same problem as described above,
A plurality of file browsing programs specialized for the file type are stored in advance in the program storage means,
When the selection operation of the file to be browsed and displayed is detected by the selection operation detection unit of the computer, the file type of the file is determined by the file type determination unit of the computer,
The browsing program selection unit of the computer selects the browsing program corresponding to the file type as an execution target, and the browsing program execution unit of the computer executes the file browsing program selected by the browsing program selection unit. on the other hand,
When the browsing program execution means detects the end of the file, and while the browsing program is executed by the browsing program execution means, the computer's execution program automatic termination means changes the file type from the file type determination means. When the notification is received, the file browsing program executed by the browsing program execution unit is automatically terminated by the execution program automatic termination unit.
Further, the file automatic selection means of the computer automatically selects a file to be browsed and displayed from a designated folder according to a predetermined order, and the execution program automatic termination means replaces the file type notification. Then, when an instruction to select the next file is detected, the file browsing program executed by the browsing program execution means may be automatically terminated.

  The file browsing apparatus, the file browsing control program, and the file browsing method of the present invention provide a file browsing program corresponding to the file type at the time when a selection operation of the file to be browsed is detected by the selection operation detecting means. When the browsing program execution means detects the end of the file, and when the browsing program execution means detects the end of the file and the browsing program is executed by the browsing program execution means, the execution program automatic termination means When a new file type notification is received from the file type determination means, that is, when the next file is predicted to be selected as a browsing target and when the next file is actually selected as a browsing target Is the file review executed by the browsing program execution means. The user program is automatically terminated, so the user selects a file browsing program to be started when browsing the file, and manually starts up the program following the startup procedure specific to the file browsing program. In order to perform or browse the next file of a different type, the currently opened file browsing program is temporarily terminated, and another file browsing program is launched by following the selection operation and the specific startup procedure again. The user can browse various types of files continuously without performing a cumbersome operation.

  In addition, since the file browsing program itself can be diverted, the time and cost required for the research and development of the program are reduced, and the user can introduce the file browsing program for image files, A single-function file browsing program such as a file browsing program for video files, a file browsing program for text files, and a file browsing program for presentation files need not be wasted.

  Next, an example is given about the best form for implementing this invention, and it demonstrates in detail with reference to drawings.

  FIG. 1 is a functional block diagram showing a simplified configuration of a file browsing apparatus 1 according to an embodiment to which the present invention is applied.

  As shown in FIG. 1, the main part of the file browsing apparatus 1 of the present embodiment is a plurality of file browsing programs specialized for file types, such as a file browsing program for image files, a video file A program storage means A for storing a file browsing program, a file browsing program for a text file, a file browsing program for a presentation file, and a selection operation of a file G to be browsed are detected. A selection operation detection means B, a file type determination means C for determining the file type of the file G detected by the selection operation detection means B, and a file browsing program corresponding to the file type determined by the file type determination means C. Program storage means for execution The browsing program selection means D to select from, the browsing program execution means E to read and execute the file browsing program selected by the browsing program selection means D, and the browsing program execution means E end the file G The file that is being executed by the browsing program execution means E when it is detected and when the file type determination means C receives a file type notification while the browsing program execution means E executes the file browsing program It is constituted by an execution program automatic ending means F for automatically ending the browsing program.

  More specifically, the execution program automatic ending means F of this embodiment is such that the file browsing program executed by the browsing program executing means E is a file browsing program for text files or a file browsing for presentation files. In the case of a program, when the browsing program execution means E detects an EOF code, the browsing program execution means E terminates the file browsing program executed by the browsing program execution means E and is executed by the browsing program execution means E. When the file browsing program is a file browsing program for image files or a file browsing program for video files, the browsing program is executed when a notification of a new file type is received from the file type determination means C. Executed by means E It is configured so as to terminate the file browsing program that.

Strictly speaking, the EOF code here means End Of
“File” means a 1-byte control code written at the end of a file to indicate the end of a text file or presentation file. In the file browsing program for text files and the file browsing program for presentation files used when browsing files, the data written in the file is accessed sequentially and the contents are sequentially displayed on the computer display etc. Therefore, when the browsing program execution means E reads the last data of the file and tries to read the next data, this EOF code is detected. Since it is not always known whether another file (including text file and presentation file) will be selected for viewing after the viewing of the text file or presentation file, the following file will be used to detect the EOF code. It merely predicts the possibility of being selected as the target of

  Also, for example, the end of the file can be specified using metadata such as the size of the text file or the presentation file, the resource fork of the file, etc. Therefore, it is not always necessary to write the EOF code at the end of the file. It is not a requirement.

  On the other hand, there is no concept corresponding to an EOF code in an image file or a video file, and it is predicted that the next file may be selected as a browsing target while the browsing program execution means E reads the file data. In these cases, since the browsing program execution means E is reading the file data, a new file is actually selected as a browsing target, and the execution program automatic termination means F determines the file type. It is necessary to recognize that the next file has been selected as a browsing target by receiving the notification of the new file type from the means C.

  The function of the file type determination means C is already known. For example, the file type of the file can be easily determined by referring to the extension attached to the file, metadata of the file, resource fork, or the like.

[Embodiment 1]
FIG. 2 is a block diagram showing an outline of a configuration of a computer 2 in which the file browsing apparatus 1 of the embodiment is integrally mounted.

  The computer 2 is, for example, a personal computer or a workstation, and includes a microprocessor 3 for arithmetic processing, a ROM 4 storing a basic control program for the microprocessor 3, and an operation system for overall control of the computer 2. A hard disk drive 5 storing various application programs and various files and various data, a RAM 6 used for temporary storage of calculation data, and an interface 7 for connecting to various peripheral devices and network systems, A keyboard 9, a mouse 10, and a display 11 that function as a man-machine interface are connected to an input / output circuit 8 of the microprocessor 3.

  The hard disk drive 5 of the present embodiment also functions as program storage means A for storing a file browsing program. The hard disk drive 5 includes a file browsing program for image files and a file browsing for video files. Various file browsing programs such as a file browsing program, a text file browsing program, and a presentation file browsing program are stored in advance as application programs, and the microprocessor 3 of the computer 2 is connected to the file browsing apparatus 1. “File” for functioning as selection operation detection means B, file type determination means C, browsing program selection means D, browsing program execution means E, and execution program automatic termination means F Browsing control program "(see FIG. 3) are stored.

  A file browsing program for an image file, a file browsing program for a video file, a file browsing program for a text file, and a file browsing program for a presentation file that are functioning independently are already known and various programs are already available. Since it is commercially available, it will not be described here.

  A file browsing apparatus 1 comprising a selection operation detection unit B, a file type determination unit C, a browsing program selection unit D, a browsing program execution unit E, and an execution program automatic end unit F is a known image file that functions alone. File viewing program, video file viewing program, text file viewing program, presentation file viewing program, etc., in cooperation with each other. This is realized by a “file browsing control program” (see FIG. 3) stored in the microprocessor 3 and the hard disk drive 5.

  FIG. 3 shows a state in which the “file browsing control program” is activated, that is, the file browsing mode is selected, the selection operation detecting means B, the file type determining means C, the browsing program selecting means D, and the browsing program executing means E. 4 is a flowchart showing an outline of the processing operation of the microprocessor 3 functioning as the execution program automatic end means F.

  Next, the file browsing apparatus 1, the file browsing control program, and the file browsing method of this embodiment will be specifically described with reference to FIG.

  FIG. 4 is a conceptual diagram showing an example of a file stored in the hard disk drive 5.

  Here, an image file G1, a video file G2, a text file G3, a presentation file G4, etc. are already stored in the folder 13 under the folder 12 of the data storage area in the hard disk drive 5, and these files are stored by the user. It is assumed that selections are made in an arbitrary order according to the intention and displayed on the display 11 of the computer 2 for continuous browsing.

  Therefore, when a user who browses the file operates the keyboard 9 or mouse 10 functioning as a man-machine interface to start the “file browsing control program”, the microprocessor 3 first displays the display 11 in FIG. Such a file selection window 14 and a file browsing window 15 are displayed (step S0), and a standby state is waited for the user to select a file to be browsed (step S1).

  The file selection window 14 is a window for selecting a file to be browsed, and the file browsing window 15 is a window for browsing the contents of the file.

  The selection operation of the file to be browsed can be easily realized by, for example, an operation such as placing the cursor 16 on the position of the file to be browsed in the file selection window 14 and clicking the mouse 10.

  When the user selects a file to be browsed, the microprocessor 3 functioning as the selection operation detection unit B detects this selection operation (step S1), and then the microprocessor 3 functioning as the file type determination unit C The file type of the file selected in step S1 is determined (step S2).

  As described above, the file type can be easily determined by referring to the extension attached to the file, file metadata, file resource fork, or the like.

  Here, if the file selected by the user in the process of step S1 is the image file G1, the microprocessor 3 functioning as the browsing program selection means D is replaced with the hard disk drive 5 functioning as the program storage means A. A microprocessor that functions as browsing program execution means E by reading a file browsing program for an image file specialized for browsing display of an image file from the image file and developing it as an execution target program in the RAM 6 that functions as a work memory (step S3). 3 starts processing according to the file browsing program for the image file (step S4), and the microprocessor 3 functioning as the selection operation detecting means B detects that another file has been selected as a browsing target again. Until it is Flop see S6), continues to display the images of the image files G1 based on the data of the image file has been selected G1 file viewing window 15 of the display 11 (step S5).

  When viewing an image file, unlike the case of viewing a text file or presentation file, it is necessary to read the image data for one file all the way to the end and perform display output for viewing. Detecting the end of the image file, the file browsing program for the image file will be terminated simultaneously with the completion of reading the image data, causing inconvenience in the image display. Instead of this processing, the file browsing program for the image file is terminated after waiting for selection of a new file.

  When the file selected in the process of step S1 is the video file G2, the microprocessor 3 functioning as the browsing program selection means D receives the video file from the hard disk drive 5 functioning as the program storage means A. A file browsing program for a video file specialized for browsing display is read and expanded as an execution target program in the RAM 6 functioning as a work memory (step S3), and the microprocessor 3 functioning as browsing program execution means E is The processing according to the file browsing program for the file is started (step S4), and until the microprocessor 3 functioning as the selection operation detecting means B detects that another file has been selected as the browsing target again. (See step S6) It continues to display a moving image file G2 in the file browsing window 15 of the display 11 based on the selected data of the video file G2 (step S5).

  The reason for waiting for the selection of a new file and terminating the file browsing program for the video file instead of the end detection process is as described above.

  While the microprocessor 3 functioning as the browsing program execution means E executes the file browsing program for image files and the file browsing program for video files, the user selects the file selection window 14 in the same manner as described above. When another file is selected as a browsing object by operating the cursor 16, the microprocessor 3 functioning as the selection operation detecting means B detects this selection operation (step S6) and functions as the execution program automatic ending means F. The microprocessor 3 terminates the execution of the file browsing program for image files and the file browsing program for video files, and frees the storage area of the RAM 6 that functions as a work memory (step S7).

  Next, the microprocessor 3 functioning as the file type determination unit C determines the file type of the file selected as the browsing target by the user in step S6 (step S2).

  Here, if the file selected by the user is a text file G3, the microprocessor 3 functioning as the browsing program selection means D reads the text file from the hard disk drive 5 functioning as the program storage means A. A file browsing program for a text file specialized for display is read and expanded as an execution target program in the RAM 6 functioning as a work memory (step S8), and the microprocessor 3 functioning as the browsing program executing means E reads the text file. Until the microprocessor 3 functioning as the browsing program execution means E detects the end of the text file G3, that is, the EOF code (step S11). Irradiation), read sequentially sequentially the data in the text file G3 selected, continues to display the text in a text file G file viewing window 15 of the display 11 (step S10).

  If the file selected in the process of step S6 is the presentation file G4, the microprocessor 3 functioning as the browsing program selection means D receives the presentation file from the hard disk drive 5 functioning as the program storage means A. A file browsing program for a presentation file specialized for browsing display is read and expanded as an execution target program in the RAM 6 functioning as a work memory (step S8), and the microprocessor 3 functioning as the browsing program executing means E performs presentation. The processing according to the file browsing program for the file is started (step S9), and the microprocessor 3 functioning as the browsing program executing means E loads the presentation file G4. Until the end, that is, until the EOF code is detected (see step S11), the data of the selected presentation file G4 is sequentially read and the text and image of the presentation file G4 are displayed in the file browsing window 15 of the display 11. Continue (step S10).

  The microprocessor 3 functioning as the browsing program execution means E while the microprocessor 3 functioning as the browsing program execution means E executes the file browsing program for text files and the file browsing program for presentations. When the end of the text file G3 or the presentation file G4, that is, the EOF code is detected (step S11), the microprocessor 3 functioning as the execution program automatic termination means F reads the file browsing program for the text file and the file browsing for the presentation file. The storage area of the RAM 6 functioning as a work memory is released by terminating the execution of the program for use (step S12), and the microprocessor 3 allows the user to select a file to be viewed. It returns to the initial standby state to wait for the (step S1).

  Next, when the user selects another file as a browsing object by operating the cursor 16 in the file selection window 14 in the same manner as described above, the microprocessor 3 functioning as the selection operation detecting means B detects this selection operation. (Step S1), the microprocessor 3 functioning as the file type determination means C determines the file type of the file selected by the user in the process of Step S1 (Step S2), and the same as described above according to the determination result Processing, that is, if the selected file is an image file or a video file, the processing from step S3 to step S7, and if the selected file is a text file or a presentation file, step S8 to step S8. Step S12 is repeatedly executed It will be.

  Therefore, the processing operation required for the user when selecting the text file G3 or the presentation file G4 as the browsing target after selecting the image file G1 or the video file G2 as the browsing target is the file displayed in the process of step S0. Similarly to the file selection operation in step S1 in which the image file G1 or the video file G2 is selected with reference to the selection window 14, the text file G3 or presentation file G4 to be browsed next is referred to with reference to the file selection window 14. This is only the file selection operation in step S6.

  On the contrary, the processing operation required for the user when selecting the image file G1 or the video file G2 as the browsing target after selecting the text file G3 or the presentation file G4 as the browsing target is as follows. Similarly to the file selection operation in step S1 in which the text file G3 or the presentation file G4 is selected with reference to the file selection window 14 displayed in the process, the next image to be browsed with reference to the file selection window 14 Only the file selection operation in step S1 for selecting the file G1 or the video file G2 is sufficient.

  Further, the processing operation required for the user when selecting another image file or video file as the browsing target after selecting the image file or video file as the browsing target is the file selection displayed in the process of step S0. Similarly to the file selection operation of step S1 for selecting an image file or a video file with reference to the window 14 for use, similarly to step S6 for selecting an image file or a video file to be browsed with reference to the file selection window 14 This is only the file selection operation.

  The processing operation required for the user when selecting another text file or presentation file as a browsing target after selecting the text file or presentation file as the browsing target is the file selection displayed in step S0. Similarly to the file selection operation in step S1 for selecting a text file or a presentation file with reference to the window 14 for use, similarly to step S1 for selecting the text file or presentation file to be browsed next with reference to the file selection window 14 Only the file selection operation is required.

  Both the determination process of step S1 and the determination process of step S6 are merely performed by detecting the alignment of the cursor 16 or the click operation of the mouse 10 performed in the file selection window 14, and the user can There is no need to distinguish the difference between the determination process of step S1 and the determination process of step S6.

  That is, regardless of the order in which the image file, the video file, the text file, and the presentation file are browsed in succession, the user simply wants to browse next by referring to the file selection window 14. Various files of different types can be browsed continuously by a simple operation of selecting a file by clicking the mouse 10 or the like.

  In addition, the processes in steps S3 to S4 and the processes in steps S8 to S9 are equivalent to the startup of a file browsing program that functions alone, and the processes in step S5 and step S10 function independently. Since this process is implemented using the functions of the file browsing program itself, it is possible to browse files using the existing file browsing program effectively. Cost is reduced, and from the user's point of view, a file browsing program for image files, a file browsing program for video files, a file browsing program for text files, presentation files Single-function file such as a file browsing program It can be utilized without abandoning Le browsing program.

  There is no need to start or end the file browsing program using a window unique to each file browsing program, and refer to the file display in the file selection window 14 even for files of different types. It can be easily selected as a browsing target, and there is no need to switch between windows when starting and ending a file browsing program, and even when selecting a file, so various files of different types can be browsed smoothly. .

  As described above, as an embodiment, the case where four types of files such as an image file, a video file, a text file, and a presentation file are to be browsed has been described. However, a file browsing program suitable for the file type, a file type, and a file browsing If the hard disk drive 5 stores only the association with the program for use, it is possible to cope with browsing of various other types of files.

[Embodiment 2]
Next, an embodiment will be described in which files in a designated folder can be browsed sequentially and fully automatically according to a predetermined order.

  FIG. 6 is a functional block diagram showing a simplified configuration of the file browsing apparatus 1 according to another embodiment to which the present invention is applied.

The main components are the same as those of the file browsing apparatus 1 (see FIG. 1) of the above-described embodiment. However, in this embodiment, a file to be browsed and displayed according to a predetermined order from a designated folder. A file automatic selection means H for automatically selecting the file is provided.
In addition, the execution program automatic end means F of this embodiment receives an instruction to select the next file by the user's operation with the mouse 10 or the like in addition to the case where the browsing program execution means E detects the end of the file. In this case, the file browsing program executed by the browsing program execution means E is automatically terminated.

  The hardware configuration of the computer 2 in which the file browsing device 1 of this embodiment is integrally mounted is the same as that shown in FIG. 2, but the “file browsing control program stored in the hard disk drive 5 of the computer 2 is used. (See FIG. 7) is different from the above-described embodiment.

  The function of the automatic file selection means H is realized by a “file browsing control program” (see FIG. 7) stored in the microprocessor 3 and the hard disk drive 5 of the computer 2.

  Regarding the ordering of files in a folder, ordering according to the character code of the file name, ordering according to the file type, ordering according to the file type, ordering according to the file capacity, ordering according to the file creation date In addition, there is a known ordering that combines them, and this sort function is already implemented in a general computer 2 and will not be described here.

  FIG. 7 shows a state in which the “file browsing control program” of the present embodiment is activated, that is, a state in which the file browsing mode is selected, the selection operation detection means B, the file type determination means C, the browsing program selection means D, and browsing 3 is a flowchart showing an outline of processing operations of a microprocessor 3 functioning as program execution means E, execution program automatic end means F, and file automatic selection means H.

  A user who browses a file operates a keyboard 9 or a mouse 10 functioning as a man-machine interface to start a “file browsing control program”, and selects a folder to be browsed, for example, the folder 13 shown in FIG. When selected, the microprocessor 3 first initializes the value of the file selection index i to 0 (step T0).

  Next, the microprocessor 3 increments the value of the file selection index i by 1 (step T1), and determines whether the value of the index i exceeds the total number n of files in the folder 13 (step T2).

  However, it is assumed that the total number n of files is already stored in the hard disk drive 5 as metadata of the folder 13.

  If the determination result in step T2 is false and it is clear that the value of the file selection index i does not exceed the total number n of files in the folder 13, the file to be browsed is still in the folder 13. Since it means that the file remains, the microprocessor 3 functioning as the automatic file selection means H browses the file whose order in the folder 13 is i-th based on the current value of the file selection index i. At the same time, the microprocessor 3 functioning as the selection operation detection means B detects the completion of the selection process (step T3).

  Next, the microprocessor 3 functioning as the file type determination means C determines the file type of the file selected in the process of step T3 (step T4).

  If the order of the files in the folder 13 is as shown in the example of FIG. 4 such as an image file G1, a video file G2, a text file G3, and a presentation file G4, the value of the file selection index i is At this time, the image file G1 is selected as a file to be browsed.

  In this case, the microprocessor 3 functioning as the browsing program selection means D reads the file browsing program for the image file specialized for the browsing display of the image file from the hard disk drive 5 functioning as the program storage means A to read the work memory. Is expanded as a program to be executed in the RAM 6 functioning as (step T5), and the microprocessor 3 functioning as the browsing program execution means E starts processing according to the file browsing program for image files (step T6). Until an instruction to automatically select the next file is detected by the microprocessor 3 functioning as the execution program automatic ending means F (see step T8), the image file is displayed on the display 11 based on the data of the selected image file G1. G1 It continues to display an image (step T7).

  The reason why the file browsing program for image files is terminated after waiting for an instruction to automatically select the next file is as described above.

  Then, while the microprocessor 3 functioning as the browsing program execution means E executes the file browsing program for the image file, an instruction to automatically select the next file as a browsing target, for example, clicking the mouse 10 When the user executes an operation or the like, the microprocessor 3 functioning as the execution program automatic termination means F detects this operation (step T8), terminates the execution of the file browsing program for the image file, and functions as a work memory. The storage area of the RAM 6 to be released is released (step T9).

  Next, the microprocessor 3 again increments the value of the file selection index i by 1 (step T1), and determines whether the value of the index i exceeds the total number n of files in the folder 13 (step T2).

  Since the current value of the file selection index i is 2, the determination result in step T2 is false, and the microprocessor 3 functioning as the file automatic selection means H uses the folder 13 based on the current value of the file selection index i. Automatically selects the video file G2 with the i-th order, that is, the second, as the file to be browsed, and at the same time, the microprocessor 3 functioning as the selection operation detection means B detects the completion of the selection process. (Step T3).

  Next, the microprocessor 3 functioning as the file type determination means C determines the file type of the file newly selected in the process of step T3 (step T4).

  In this case, since the value of the file selection index i is 2 and the video file G2 is selected as the file to be browsed, the microprocessor 3 functioning as the browsing program selection means D functions as the program storage means A. A file browsing program for video files specialized for video file browsing display is read from the hard disk drive 5 and expanded as an execution target program in the RAM 6 functioning as a work memory (step T5), and functions as browsing program execution means E. The microprocessor 3 that starts the process according to the file browsing program for the video file (step T6), and an instruction to automatically select the next file is detected by the microprocessor 3 that functions as the execution program automatic end means F. Until Tsu see flop T8), continues to display the video image files G2 on the display 11 based on the data of the video file is selected G2 (step T7).

  The reason why the file browsing program for video files is terminated after waiting for an instruction to automatically select the next file is as described above.

  Then, while the microprocessor 3 functioning as the browsing program execution means E executes the file browsing program for the video file, an instruction to automatically select the next file as a browsing target, for example, clicking the mouse 10 When the user executes an operation or the like, the microprocessor 3 functioning as the execution program automatic termination means F detects this operation (step T8), terminates the execution of the file browsing program for the video file, and functions as a work memory. The storage area of the RAM 6 to be released is released (step T9).

  Next, the microprocessor 3 again increments the value of the file selection index i by 1 (step T1), and determines whether the value of the index i exceeds the total number n of files in the folder 13 (step T2).

  Since the current value of the file selection index i is 3, the determination result in step T2 is false, and the microprocessor 3 functioning as the file automatic selection means H uses the folder 13 based on the current value of the file selection index i. The text file G3 with the i-th order, that is, the third is automatically selected as the file to be browsed, and at the same time, the microprocessor 3 functioning as the selection operation detection means B detects the completion of the selection process. (Step T3).

  Next, the microprocessor 3 functioning as the file type determination means C determines the file type of the file newly selected in the process of step T3 (step T4).

  In this case, since the value of the file selection index i is 3 and the text file G3 is selected as the file to be browsed, the microprocessor 3 functioning as the browsing program selection means D functions as the program storage means A. A file browsing program for text files specialized for text file browsing display is read from the hard disk drive 5 and expanded as an execution target program in the RAM 6 functioning as a work memory (step T10), and functions as browsing program execution means E The microprocessor 3 that starts the processing according to the file browsing program for the text file (step T11), and the microprocessor 3 that functions as the browsing program execution means E starts the end of the text file G3, that is, the EOF code. The until the detection (see step T13), reads sequentially sequentially the data in the text file G3 selected, continues to display the text in a text file G3 on the display 11 (step T12).

  While the microprocessor 3 functioning as the browsing program execution means E executes the file browsing program for the text file, the microprocessor 3 functioning as the browsing program execution means E detects the end of the text file G3, that is, the EOF code. Is detected (step T13), the microprocessor 3 functioning as the execution program automatic end means F terminates the execution of the file browsing program for the text file and releases the storage area of the RAM 6 functioning as a work memory (step S13). T9).

  Next, the microprocessor 3 again increments the value of the file selection index i by 1 (step T1), and determines whether the value of the index i exceeds the total number n of files in the folder 13 (step T2).

  Since the current value of the file selection index i is 4, the determination result in step T2 is false, and the microprocessor 3 functioning as the file automatic selection means H uses the folder 13 based on the current value of the file selection index i. Automatically selects the presentation file G4 with the i-th order, that is, the fourth, as the file to be browsed, and at the same time, the microprocessor 3 functioning as the selection operation detection means B detects the completion of the selection process. (Step T3).

  Next, the microprocessor 3 functioning as the file type determination means C determines the file type of the file newly selected in the process of step T3 (step T4).

  In this case, since the value of the file selection index i is 4 and the presentation file G4 is selected as the file to be browsed, the microprocessor 3 functioning as the browsing program selection means D functions as the program storage means A. A file browsing program for presentation files specialized for presentation file browsing display is read from the hard disk drive 5 and expanded as an execution target program in the RAM 6 functioning as a work memory (step T10), and functions as browsing program execution means E The microprocessor 3 to start starts processing according to the file browsing program for presentation files (step T11).

  Since the browsing display of the presentation file is the same as that of the text file described above, detailed description thereof is omitted.

  In this embodiment, the microprocessor 3 automatically selects the next file only when the file automatically selected by the file automatic selection means H as an object for browsing display is an image file or a video file. The user is requested to click the mouse 10 or the like. Except for this point, one folder, for example, the files in the folder 13 are sequentially and all in accordance with a predetermined order. It is possible to browse automatically.

  As already mentioned, the order according to the character code of the file name, the order according to the file type, the order according to the file type, the order according to the file capacity, the order according to the creation date of the file, Functions such as combined ordering have already been implemented in the general computer 2, so that the user can browse a large number of files in the folder 13 in order and continuously according to various sorting methods by selecting a sorting method. it can.

  Finally, when the browsing display of the file whose sorting order is the last is started, the value of the file selection index i matches the value of the total number n of files in the folder 13 (see step T2). After the browsing display related to is performed in the same manner as described above (see step T3 to step T9, or step T3 to step T4, step T10 to step T13, step T9), the value of the file selection index i is incremented by 1 again. At this stage (see step T1), the value of the index i exceeds the value of the total number n of files (see step T2), and the series of “file browsing control program” ends.

  For example, if there are four files in the folder 13: an image file G1, a video file G2, a text file G3, and a presentation file G4, since the value of n is 4, the browsing display of the presentation file G4 is started. At this point, the index i value is 4, and the browsing display of the presentation file G4 is completed in the process of step T9. When the value of the file selection index i is incremented by 1 and becomes 5, the “file viewing index” is displayed. The “control program” ends.

  As in the case of the above-described embodiment, the processing from step T5 to step T6 and the processing from step T10 to step T11 are processing equivalent to the startup of a file browsing program that functions independently, and the processing from step T7 to step T12. Since this process is realized by using the function of the file browsing program itself that functions independently, it is possible to browse the file effectively using the existing file browsing program, The time and cost required for research and development of the image file is reduced, and from the user's side, the file browsing program for image files, the file browsing program for video files, and the text file File browsing program, file browsing program for presentation files It can be used without having to abandon the single-function file-viewing program, such as arm.

  As in the case of the above-described embodiment, there is no need to start and end the file browsing program using a window specific to each file browsing program. In particular, in this embodiment, file selection is performed. Since the operation itself is automatically performed by the file automatic selection means H in accordance with the ordering determined by the sorting function of the computer 2, the user does not need to select a file, and various types of files can be handled very smoothly. Can be viewed.

  In particular, since the file automatic selection means H automatically selects the files in the designated folder in order, the file can be browsed even when the user creates a digest by browsing many files in the folder. There is no concern that leakage will occur and there are advantages such as improved usability of the device.
