fdupes is a program written by Adrián López to scan directories for duplicate files,[2] with options to list, delete or replace the files with hardlinks pointing to the duplicate. It first compares file sizes, partial MD5 signatures, full MD5 signatures, and then performs a byte-by-byte comparison for verification.
