This program uses CRC32 to compute hashes. This is a terrible idea - a 32bit hash is just too short and the probability of collisions is way too high. Only a few thousand files are enough to get 50% probability of a collision. Even though this is decreased by additional matching by extensions and sizes, I wouldn't trust it to delete any files. Use fclones, fslint, jdupes, rdfind instead, which either use much stronger hashes (128-bit) or even verify files by direct byte-to-byte comparison.
