File association processing device, file association method, and file association program

摘要

PROBLEM TO BE SOLVED: To provide a file association processing device, a file association method, and a file association program capable of tracking the relationship between files. A file association processing device (10) includes a calculation unit (16) that calculates a hash value of a file (30) in a format in which a hash value can be written, and a writing unit (18) that writes the hash value into a file (30) different from the file (30). An acquisition unit 20 that acquires the hash value from the file 30 in which the hash value is written, and the hash value acquired by the acquisition unit 20 from one file 30 and the calculation from another file 30. The hash value calculated by the unit 16 is collated, and when the hash value of the one file 30 and the hash value of the other file 30 match, the one file 30 and the other file 30 Associate with.
