<p>A duplicate file detection device 100 has a storage unit 101, a calculation unit 102, and a detection unit 103. The storage unit 101 stores calculation information that defines data used in the calculation of the hash values of files in association with the extensions of the files. The calculation unit 102 acquires the calculation information associated with the extension of each file to be examined from the storage unit 101 and uses the acquired calculation information to calculate the hash value of each file to be examined. The detection unit 103 detects duplicated files by comparing the hash values of the files to be examined that are calculated by the calculation unit 102.</p> |
