HashMyFiles is an utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system. You can easily copy the MD5/SHA1 hashes list into the clipboard, or save them into text/html/xml/csv file.
To install automatically HashMyFiles on your LiberKey, make sure you previously activated files associations from the "LiberKey Tools" menu.
You can then open the file directly to start the installation.
