HashMyFiles a freeware tool to compare file content using MD5, SHA1 and CRC32 Video
This is a quick look at HashMyFiles, an excellent freeware tool that will display a unique MD5, SHA1 or CRC32 hash from your files. This is very handy when you want to compare the exact content of some files. It has a handy drag and drop interface and is pretty quick at generating the hashes. You can also copy or export the hashes to a text/html/xml file and there is an option to enable the utility as a contextual menu. The tool does not require installation. In the video I mention being able to determine a file is exact, but of course this unique hash could be faked; from a security perspective MD5 is less secure that SHA1 due to the length of the hash but as with everything online always scan files for viruses and malware to be certain.
