The present invention has been made in view of such circumstances, and can hierarchically display data such as image files recorded in a non-rewritable recording medium such as a CD-R. An object of the present invention is to provide a file display device that can perform file operations such as moving and deleting files, and can display the file in the state of the previous file operation when the file of the next recording medium is displayed.
[0007]
[Means for Solving the Problems]
In order to achieve the object, the invention according to claim 1 is written with a plurality of files, a script file having information indicating the correspondence between the real folder hierarchy of the file and the virtual folder hierarchy, and unique identification information. A file display device for displaying a file on a non-rewritable recording medium, a storage means for storing the script file, a reading means for reading information on the recording medium, and when the recording medium is attached to the reading means, A determination means for determining whether or not a script file having the same identification information as the identification information of the script file recorded on the recording medium is stored in the storage means; Then, based on the script file recorded on the recording medium, the virtual Display means for displaying a virtual folder hierarchy based on a script file having the same identification information stored in the storage means when it is determined that the display hierarchy is stored in the storage means, and the display It has been moved files in the virtual folder hierarchy, delete, delete folders, and the folders operation means for enabling file operations including the creation of a new folder, the file operation is performed by the folder operation means, file operation Control means for storing a script file having a later virtual folder hierarchy in the storage means.
[0008]

[0009]
When the recording medium is mounted on the reading means, it is determined whether or not a script file having the same identification information as the identification information of the script file in the recording medium is stored in the storage means. If it is determined that it is not stored, the virtual folder hierarchy is displayed based on the script file recorded on the recording medium, and if it is determined that it is stored, it is stored in the storage means. A virtual folder hierarchy is displayed based on script files having the same identification information.
[0010]
File operations such as creating a new folder, deleting a folder, moving a file, and deleting a file can be performed in the displayed virtual folder hierarchy, and a script file having a result of the file operation is stored in the storage means. As a result, the next time the recording medium on which the file operation is performed is loaded, the virtual folder hierarchy can be displayed based on the script file stored in the storage means, and the browsing of the optimized recording medium can be performed. Is possible.
[0011]
Since the virtual folder hierarchy is associated with the actual folder hierarchy, a file on the recording medium can be opened by designating a desired file on the virtual folder hierarchy.
[0012]
According to a second aspect of the present invention, the control unit causes the recording unit to overwrite and save a script file recorded on the recording medium when there is an instruction input to return to the virtual folder hierarchy of the recording medium. .

And a means for rearranging and displaying the hierarchy.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a file display device according to the present invention will be described in detail with reference to the accompanying drawings.
[0015]
FIG. 1 is a block diagram showing a hardware configuration example of a file display apparatus according to the present invention.
[0016]
As shown in FIG. 1, this file display device is composed of, for example, a personal computer or the like, and mainly stores a central processing unit (CPU) 10 that controls the operation of each component and a control program for the device, or when a program is executed. A main memory 12 serving as a work area, a PC operating system (OS), a file display program, various application software, a hard disk device 14 storing user images, etc., reading from a CD-ROM and CD-ROM A CD-R / RW device 16 capable of reading and writing to R, a display memory 18 for temporarily storing display data, and a CRT monitor for displaying images, characters, etc. by image data, character data, etc. from the display memory 18 And a monitor device 20 such as a liquid crystal monitor, a keyboard 22, and a mouse 24 as a position input device. A mouse controller 26 that detects the state of the mouse 24 and outputs signals such as the position of the mouse pointer on the monitor device 20 and the state of the mouse 24 to the CPU 10, and a bus 28 that connects the above components. .
[0017]
Since the personal computer having the above-described configuration is a well-known computer except for the file display program stored in the hard disk device 14, a detailed description of each component will be omitted.
[0018]
Next, the recording structure of the recording medium (CD-R) according to the present invention will be described.
[0019]
When a user designates a folder in which image files are stored in a lower layer on the hard disk device 14 and the backup to the CD-R is instructed, a predetermined album creation program causes all layers below the folder to be stored in the CD-R. After being arranged into CD writing data suitable for recording on the R, the data is written on the CD-R by the CD-R / RW device 16.
[0020]
FIG. 2 is a diagram showing a state in which the recording structure is converted from the tree structure of the hard disk device 14 to the tree structure of CD writing data.
[0021]
For example, when a folder “TestData” is selected from the tree structure of the hard disk device 14 shown in FIG. 2A, the folders and image files under this folder are converted into a recording structure as shown in FIG. Is done.
[0022]
That is, DCF folders (100_FUJI, 101_FUJI) in the same hierarchy are created immediately below the DCF image root directory DCIM (Digital Camera IMages), and image files corresponding to the DCF folders are copied.
[0023]
In addition, the folder name and the file name are automatically generated and attached to the DCF folder and the image file created in this way based on a predetermined naming rule.
[0024]
In this embodiment, folder names and file names are automatically generated based on DCF (Design rule for Camera File system) specifications, and folder names and file names are renamed into a format that is easy to manage. Yes.
[0025]
The CD-R includes information indicating the correspondence between the DCF-defined real folder hierarchy on the CD-R and the folder hierarchy (virtual folder hierarchy) before the recording structure conversion, and the unique ID (Identification) of the CD-R. ) Is written as a script file. FIG. 3 shows a description example of the script file. The unique ID on FIG. 3 indicates the date and time of writing on the CD-R, and indicates that the date and time of writing was 2001/12/26 19:37:40.
[0026]
Next, file operation and display control on the CD-R will be described.
[0027]
As shown in the flowchart of FIG. 4, it is determined whether or not the CD-R on which the CD writing data including the script file is recorded is inserted into the CD-R / RW device 16 (step S10). Is inserted, the unique ID of the CD-R is read (step S12).
[0028]
Subsequently, it is determined whether or not a script file whose unique ID matches the read unique ID is stored in an internal memory of the file display device (for example, a storage area for storing the script file of the hard disk device 14) ( Step S14).
[0029]
If a script file with a unique ID is stored in the internal memory, the script file with a unique ID is read from the internal memory (step S16), and the script file with a unique ID is stored in the internal memory. If not (when the CD-R is inserted for the first time), the script file is read from the CD-R (step S18).
[0030]
Next, a virtual folder hierarchy is displayed based on the read script file, and file operations, display of the main image of the image file, and the like are performed (step S20).
[0031]
FIG. 5 shows a virtual folder hierarchy displayed on the monitor device 20 based on the script file shown in FIG. 3, and the “Day 1” folder is selected and “Coast.JPG” and “Island.FPX” are selected. It shows about the case where the image file of is displayed.
[0032]
Here, as shown in FIG. 6, by dragging and dropping the “coast.JPG” image file to the “sea bathing” folder, the image file can be moved within the virtual folder hierarchy. The file operation is not limited to moving the image file, but a new folder can be created, a folder can be deleted, and a file can be deleted.
[0033]
In addition, when the image file of “Isojima.FPX” is clicked on FIG. 5, it is uniquely identified by the file path (101-0002) (see FIG. 3) on the CD-R associated with this virtual file path. Image files can be opened and images can be displayed.
[0034]
Returning to FIG. 4, in step S <b> 22, it is determined whether or not to end the file display, and when there is an instruction input to end the file display, there is an instruction input to return the virtual folder hierarchy to the initial state. Is determined (step S24).
[0035]
If there is no instruction input for returning the virtual folder hierarchy to the initial state, it is determined whether or not a file operation or the like has been performed in step S20 (step S26). The script file is updated to a script file having a virtual folder hierarchy after the file operation (step S28).
[0036]
For example, as described above, when a file operation for moving the image file of “coast.JPG” to the “sea bathing” folder is performed (see FIG. 6), the script file shown in FIG. 3 becomes the script file shown in FIG. To be rewritten. When a file operation is performed at the time of inserting the first CD-R, a script file having a virtual folder hierarchy after the file operation is stored in the internal memory.
[0037]
Further, when an image file is opened and the image is displayed on the monitor device 20, the history of the display count is also recorded in the script file. When a file operation for deleting the image file is performed, a flag indicating the file deletion is set in the script. Recorded in a file.
[0038]
FIG. 8 shows a script file that is updated when the image file of “Isojima.FPX” is displayed once and the image file of “Mountain Top.tif” is deleted. In the figure, the number indicates the number of times of display, and “−1” indicates a file deletion flag.
[0039]
Now, when the script file shown in FIG. 8 is read from the internal memory as a script file in which the CD-R is inserted and the unique ID matches, the virtual folder hierarchy shown in FIG. 9 is displayed. Become.
[0040]
That is, according to the display frequency history described in the script file, the virtual folder hierarchy is rearranged and displayed in preference to the one with the highest display frequency. In this example, the image file number of “Isojima.FPX” is the most frequently displayed (see FIG. 8), so the folder containing the image file of “Isojima.FPX” in the lower hierarchy is higher than the other folders. Is displayed.
[0041]
Also, the image file of “Mountain Peak.tif” having the file deletion flag “−1” is not displayed even when the “Mountain Peak” folder is clicked.
[0042]
Returning to FIG. 4, when no file operation or the like is performed in step S26, the script file in the internal memory is terminated without being updated. If no file operation is performed when the CD-R is inserted for the first time, the script file recorded on the CD-R is stored in the internal memory as it is.
[0043]
On the other hand, if there is an instruction input to return the virtual folder hierarchy to the initial state in step S24, the script file recorded on the CD-R is overwritten and saved regardless of whether or not the file operation is performed, thereby the virtual folder hierarchy. Can be returned to the initial state (step S30).
[0044]
【The invention's effect】
As described above, according to the present invention, data such as image files recorded in a non-rewritable recording medium such as a CD-R can be hierarchically displayed, and files and folders can be moved and deleted. In addition, when the next recording medium file is displayed, the recording medium can be browsed with the previous file operation (optimized state). Further, even with the same recording medium, different script files can be created according to the file operation results for each file device, and a variety of display forms can be provided.
