This software is a fast and versatile file checksum tool that supports various algorithms including MD2, MD4, MD5, SHA-1, SHA-2, RIPEMD-160, TIGER, PANAMA, CRC-32, ADLER32 and the hash used in eMule/eDonkey(ed2k). It is compatible with popular tools such as md5sum, Easy MD5 Creator, SFV Checker/Verifier, and Win CRC32.

This software is ideal for checking files for data corruption and maintaining data integrity. To ensure file integrity, it is recommended to perform a hash/checksum calculation on data before transferring (downloading/uploading) it from one location to another. Upon completing the download/upload process, a similar calculation is done and the former and latter results are compared to check if the received data is corrupt or not. FSUM provides notifications about any bad, incorrect, or missing files.
This software is fast and user-friendly providing users with an easy to navigate interface. It also allows the user to recurse directories and work with large size files. FSUM is compatible with .MD5 and .SFV file formats, automatically recognizing the format when verifying, and supports md5sum, MD5Summer, Easy MD5 Creator, SFV Checker/Verifier, WinSFV, and Win CRC32.
