Claims (1)

[Claims for Utility Model Registration] In addition to receiving from the operator a source specification command that specifies a source device, a destination specification command that specifies a destination device, and an end command that instructs termination, all files in the source device are A command processing unit that outputs a copy execution command to copy to the destination device and terminates the copy when an end command is input, and a command processing unit that reads the file size of the source device when the copy execution command is input. Then, determine whether the buffer area of that size can be used or not, and if possible, secure the buffer area of that size, and if it is not possible, secure the buffer area of the usable size and divide the file into that size, and then When copying a file from the source device or part of the divided file to the buffer area, then copying the file or part of the file copied to the buffer area to the destination device, and dividing the file. 1. A file copying device comprising: a copy execution unit that repeats this process to copy one file.
