MD5 Checker Version 2.20 - 19th July 2006 Free utility to verify downloads with an MD5 checksum from the makers of MidWavi Pro (it's only 97K and this is a true Windows program!). Tiny (97K unzipped) full Windows program to verify (and create) MD5 checksums (that is, where an MD5 code is given for a download file, using this software, if the codes match, the download is good).. You can also create your own MD5 checksum if required. The download is 24K (yes 24K) and the resulting program once unzipped is a tiny 97K!!!
