FR: File hashing

[vatterspun]

I often edit lots and lots of small files over the course of a day. Even small losses of data can be hugely problematic and, as a result, I use AutoVer. One problem is that I often save files to either a device or a service that I don't really trust (see #1). As such, it would be ideal to have some method to check all files via a hashing method. There are a few ways to do this:

• Add CRC hash to file name for quick verification
• Save a hash next to each file (so for filename1.zip; filename1.zip.sfv... filename2.zip; filename2.zip.sfv, etc.)
• Save a single hash with a list of all hashes

Workaround: save all files locally, use a hashing program like RapidCRC Unicode, and then save to an external source.
