PROBLEM TO BE SOLVED: To shorten time required for file transfer even in the case where a file number or a file size becomes larger, and to efficiently perform file transfer even in the case of a file having low compression efficiency.SOLUTION: A file compression aggregation program includes: a transfer file specifying program which specifies a file to be transferred; an extension reading program which reads an extension of the file; a compression execution mapping information reading program which reads compression execution mapping information having the extension of the file, a compression method, trial counts of compression processing, and average compression rate; a compression method determination program which determines a compression method of the file out of static compression, dynamic compression and no compression on the basis of the compression method; a compression processing program; a file continuous aggregation size determination program which determines whether or not aggregation is performed or a new file is created on the basis of a size of an aggregated file; and a file creation/connection program which creates/connects a file on the basis of the determination of the file continuous aggregation size determination section. |
