    How to compare two files.

    What is the best way to do a byte by bye comparison of two large files - Windows 10 64 bit.

    There is an FC command but when run in the Power Shell I think it wants to do a 'Format Custom'!

    Thanks, I have just tried that. Unfortunately it has a 2GB limit. The files I want to compare are Windows image back up files and are more like 25GB.

    Use a tool that calculates a check sum like MD5 or SHA. I use a tool called Hash Tab which conveniently integrates itself into the file properties dialogue. It supports various check sums. If the check sums match the files must be the same, otherwise you can be sure that they are not the same.
