DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file copying method, and more particularly to a file copying method in a file system of a computer.

[0002]

2. Description of the Related Art Hitherto, when copying a plurality of files on a large-capacity medium to a plurality of small-capacity media, a human has
The file information of the copy source medium is output, and the capacity of each file and the capacity of the copy destination medium are calculated and copied. Alternatively, a plurality of small-capacity media are treated as one medium and copied.

[0003]

As described above, in the conventional technology, there is a problem that a lot of work is performed by humans, which is troublesome.

In some cases, all files cannot be copied even though the capacity of the copy source is smaller than the capacity of the copy destination.

[0005] In addition, if the capacity of the file at the copy source is larger than the capacity of the file at the copy destination, it may not be possible to copy well simply by copying the file that cannot be accommodated to the next medium.

Further, in the method of handling and copying a plurality of small-capacity media as one medium, there is a problem that a plurality of destination media cannot be used independently.

SUMMARY OF THE INVENTION An object of the present invention is to automatically copy a plurality of files on a large-capacity medium to a plurality of small-capacity media based on an appropriate copy order based on the copy destination capacity. By determining and copying, the individual media can be used independently, reducing the event that all files cannot be copied even though the capacity of the copy source is smaller than the capacity of the copy destination. It is intended to reduce the number of manual operations and the capacity of the copy destination medium.

[0008]

Select the optimal capacity file to select from the file list.
And the files registered in the copy file name list.
Source file with file name to the destination media
Copying means for copying, further comprising:
The amount detecting means is selected by the optimum capacity file selecting means.
Copy the file name and capacity of the file
File and copy source remaining file
Delete the file name and size of the file from the list
It is characterized by the following .

A file copying method includes a plurality of file adding means for repeating the optimum capacity file selecting means until there are no more files which can be accommodated in the remaining capacity of the copy destination medium, and a copy information detecting means detects a minimum capacity file. Only when the remaining file capacity is larger than the minimum capacity file, a file copying method including an addition determining step of executing the multiple file adding means,
This is the means.

[0010]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. Referring to FIG. 1, the configuration of the present invention comprises a copy information detecting means 4, a copy destination medium list 5, a copy source remaining file list 6, a copy destination remaining capacity detecting means 7,
Optimum capacity file selecting means 9, multiple file adding means 10, copy file name list 8, copying means 11,
Consists of

Next, the operation of this embodiment will be described with reference to FIG. First, when the copy destination medium 3 and the copy source medium 2 are designated from the console 1, the file name and capacity of each copy source file are registered in the copy source remaining file list 6 by the copy information detecting means 4, and the copy destination medium is registered. The name and capacity are registered in the copy destination medium list 5.

Next, the copy destination remaining capacity detecting means 7
When the files in the remaining copy source file list 6 are copied in the order in which they are registered on the first medium registered in the copy destination medium list 5, the file that can be copied in a complete form has its name changed. Move to the copy file name list 8 and register it.
Is detected by the optimum capacity file selecting means 9 from the remaining capacity of the target copy destination 3 medium and the files remaining in the copy source remaining file list 6.
The file with the smallest (copy destination remaining capacity-file capacity) being positive is detected, the information of the file is deleted from the copy source remaining list 6, and registered in the copy file name list 8.
At this time, file information of the minimum capacity is held.

Next, the remaining capacity of the copy destination is detected by the multiple file addition means 10 and the remaining capacity of the copy destination detection means 7 and, by the addition determining step, whether the held minimum capacity file can be copied to the remaining capacity of the copy destination. If it is determined that copying is possible, the optimum capacity file selecting means 9 is started again.

As a result, when there is no file that can be added, the process proceeds to the next processing without executing the addition determining step.

When there are no more files that can be copied next, the copy file name list 8 is passed to the copying means 11, and copying is performed on the first copy destination medium 3.

Next, in order to copy to the next copy destination medium 3, the same processing is repeated from the point where the copy destination remaining capacity detection means 7 is started, and when copying to the immediately preceding medium is completed, copying is performed. The copy file name list 8 is passed to the means 11 for copying.

The above processing is executed by copying source remaining file list 6
Repeat until there is no more information.

In the following, the features of the present invention will be described in detail for the case where a file is copied to two copy destination media which have the same capacity as the copy source medium when their capacities are combined.

[Embodiment 1] FIG. 2 shows an example in which there is an optimum capacity file selecting means 9 which works well. First, it is assumed that the file 1 is copied to the copy destination medium 1 and then the file 2 is to be copied. Then, since the file 2 does not fit in the remaining capacity of the copy destination medium 1, it is assumed that the most appropriate file 4 is copied from the remaining files 3, 4, and 5 to the remaining capacity of the medium 1. Since none of the remaining files are included, the files 1 and 4 are copied to the copy destination medium 1. In the meantime, a file to be copied to the copy destination medium 2 is similarly determined, and when the file copy to the copy destination medium 1 is completed, the file is copied to the copy destination medium 2 in the same manner.

As described above, according to the present invention, a file is allocated in accordance with the capacity of each copy destination file, and the efficiency is improved as compared with the conventional method in which the files are simply copied sequentially from file 1 as in the prior art. Media resources can be used well, and in particular, it is possible to reduce the occurrence of files that cannot be copied even though there is room in capacity as a whole of a plurality of copy destination media.

[Embodiment 2] FIG. 3 shows an example in which a file 1 is copied to the first copy destination medium 1 first, and then the file 2 is left. Remaining files 3,
It is selected to copy 4 and 5 repeatedly, these are copied to the copy destination medium 1, and the file 2 is copied to the copy destination medium 2.

Thus, in either embodiment,
It can be seen that the conventional method of simply copying a file that cannot be accommodated and the subsequent file to the next medium does not work.

[0024]

As described above, in the file copying method according to the present invention, when copying a plurality of files on a large-capacity medium to a small-capacity medium, the optimum capacity file selecting means selects the copy destination. By automatically determining the appropriate copy order from the capacity and copying, individual media can be used independently, and all files can be copied even though the capacity of the copy source is smaller than the capacity of the copy destination. This has the effect of reducing the event of not being able to do so, and further reducing the number of manual operations during copying and saving the capacity of the copy destination medium.
