I use File Compare XP to compare files as part of my compression/decompression tests. I find it invaluable for comparing very large files at high speed.
I would like to know if anyone knows of a better/faster FREE file compare program?File Compare XP is a small useful utility to compare file to file against several
comparison factors like extension, size, version and even CRC32.
This way you can be sure that file is the same or not.
CRC32 is very reliable way but other factors may also be important.
