CrcCheckCopy is a command-line utility for Windows and MacOS that lets you compare small or huge amounts of files in a very convenient way.
It can compare local folders, network shares, NAS folders, CDs, DVDs, external HDD drives, even folders on systems that are not connected between them.
The comparison is based on a small text file containing the CRC hashes of all the files and folders.
Two of the unique benefits of this file comparison utility is that you can send this file via email if you want to compare or verify files on a remote computer. Or you can store this text file together with your file set for future verification of its integrity.
The current version is completely free.
