Using the File Checksum extension you can create and verify checksum files.
Supported checksum files are: SFV(CRC32) , MD5 and SHA1.
You can both create and verify .sfv .md5 checksm files and also compare verification values directly.
You can verify multiple .sfv / md5 files at the same time. If you send a folder to the File Verifier it will scan that folder for all .sfv /.md5 files found.
