Abstract

PURPOSE:To save handling time for an operator while reducing such a phenomenon that all files can not be copied although the capacity of a copy destination is larger than that of a copy source at the time of copying from a large- capacity medium to plural small-capacity media. CONSTITUTION:This system consists of an optimum capacity file selecting means 9 which selects optimum files for the remaining capacity of a copy destination medium 3 detected by a copy source remaining capacity detecting means 7 according to information detected by a copy information detecting means 4 and a multiple file adding means 10 which decides whether or not the files can be added to the remaining capacity, registers the information on a copy file name list 8, and activates a copying means 11. When the files are copied from the large-capacity medium to plural small-capacity media, the capacity that the copy destination media should have is reduced, the respective media can be utilized independently, and the labor is reducible.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, when copying a plurality of files on a large capacity medium to a plurality of small capacity media, a person
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 technique, there is a problem that a lot of work is performed by a human and it takes time and effort.

In addition, even if the capacity of the copy source is smaller than the capacity of the copy destination, it may happen that all files cannot be copied.

Further, when the file capacity of the copy source is larger than the file capacity of the copy destination, there are cases where the file cannot be copied well simply by copying it to the next medium.

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

[Object of the Invention] An object of the present invention is to, when copying a plurality of files on a large-capacity medium to a plurality of small-capacity media, automatically select an appropriate copy sequence from the capacity of the copy destination. By determining and copying, individual media can be used independently, and all the files cannot be copied even if the copy source capacity is smaller than the copy destination capacity. To reduce the amount of manpower and save the capacity of the copy destination medium.

[0008]

According to the file copying method of the present invention, in the file copying method in an information processing system, a copy source file name and its capacity, and a copy destination medium name and its capacity are detected. Means, a copy source remaining file list for registering each file name of the copy source detected by the copy information detecting means and its capacity, and a medium name of the copy destination medium detected by the copy information detecting means and its Copy destination medium list for registering capacity, copy destination remaining capacity detecting means for detecting copy destination remaining capacity from the copy destination medium list, remaining capacity detected by the copy destination remaining capacity detecting means and the copy source Optimal capacity file selecting means for selecting a file having an appropriate capacity from the remaining file list and registering it in the copy file name list, and the copy file name And copying means for copying from a copy source medium based on strike the copy destination medium, as a means of file copying method characterized by having a is intended to solve the above problems.

Further, there is a file copying system including a plurality of file adding means for repeating the optimum capacity file selecting means until there are no more files to fill the remaining capacity of the copy destination medium, and the minimum capacity file is detected by the copy information detecting means. However, a file copying method including an addition determination step of executing the plural file adding means only when the remaining file capacity is larger than the minimum capacity file,
That is the means.

[0010]

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. Referring to FIG. 1, the configuration of the present invention includes a copy information detecting unit 4, a copy destination medium list 5, a copy source remaining file list 6, and a copy destination remaining capacity detecting unit 7.
Optimum capacity file selection means 9, plural file addition means 10, copy file name list 8, copy means 11,
Composed 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 copy information detecting means 4 registers the file name and capacity of each file of the copy source in the copy source remaining file list 6, and the copy destination medium. 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 copy source remaining file list 6 are copied to the medium registered first in the copy destination medium list 5 in the order in which the files are registered, the files that can be copied in the complete form have their names. The file name that is moved to the copy file name list 8 and registered only halfway, and the copy destination medium 3
Of the remaining capacity of the medium of the target copy destination 3 and the files remaining in the copy source remaining file list 6 by the optimum capacity file selection means 9.
A file having a positive (copy destination remaining capacity-file capacity) and the smallest is detected, 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, the file information of the minimum capacity is held.

Next, the plural file adding means 10 and the copy destination remaining capacity detecting means 7 detect the copy destination remaining capacity, and whether the minimum capacity file held can be copied to the copy destination remaining capacity by the addition judging step. If it is determined and copying is possible, the optimum capacity file selection means 9 is activated again.

As a result, when there is no file that can be added, the next step is performed without executing the addition determination 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 detecting means 7 is activated, and when copying to the previous medium is completed, copying is performed. The copy file name list 8 is passed to the means 11 for copying.

The above-mentioned processing is performed for the copy source remaining file list 6
Repeat until there is no more information.

The features of the present invention will be described in detail below when a file is copied to two copy destination media having the same capacity as the copy source medium when the respective capacities are combined.

[Embodiment 1] FIG. 2 shows an example in which the optimum capacity file selecting means 9 works well. First, it is assumed that the file 1 is copied to the copy destination medium 1 and then the file 2 is copied. Then, since the file 2 does not fit in the remaining capacity of the copy destination medium 1, it is assumed that the file 4 most suitable for the remaining capacity of the medium 1 is copied from the remaining files 3, 4 and 5, and further to the remaining capacity. , Files 1 and 4 are copied to the copy destination medium 1 because no remaining files can be entered. Meanwhile, a file to be copied to the copy destination medium 2 is determined in the same manner, and when the file copy to the copy destination medium 1 is completed, the file is also copied to the copy destination medium 2 in the same manner.

As described above, according to the present invention, the file is allocated according to the capacity of each copy destination file, and the efficiency is higher than that of the conventional method of simply copying from file 1 in order. It is possible to use the medium resources well, and in particular, it is possible to reduce the occurrence of a file that cannot be copied even though the plurality of copy destination media have sufficient capacity.

[Embodiment 2] FIG. 3 shows an example in which a plurality of files can be added, which works well. When the file 1 is first copied to the first copy destination medium 1, the file 2 remains. The remaining files 3,
4 and 5 are selected to be repeatedly copied, these are copied to the copy destination medium 1, and the file 2 is copied to the copy destination medium 2.

As described above, in either of the embodiments,
It can be seen that the conventional method of simply copying a file that cannot be filled up to the next medium will not work.

[0024]

As described above, in the file copying method according to the present invention, when copying a plurality of files on a medium having a large capacity to a medium having a small capacity, the optimum capacity file selecting means selects the copy destination. By automatically determining an appropriate copy order based on the capacity and copying, individual media can be used independently, and even if the copy source capacity is less than the copy destination capacity, all files are copied. This has the effect of reducing the phenomenon of being unable to do so, reducing the amount of manpower during copying, and saving the capacity of the copy destination medium.
