Turbo WinMD5 uses MD5 technology to check each file and notifies you of any potentially bad, corrupt, incorrect size, or missing files to save you hours of downloading only to find you have 1 file missing or the last file has a checksum error. The CRC value comparison is done by using a standard SFV/MD5 file. If a SFV file is not available, you can produce a new one with calculated MD5 CRC value.
