You can rename them, but MAKE SURE not to leave any spaces in the name of the folder, or your restore will fail with an MD5 checksum error.
Use period or dashes instead. An example of how I do it would be:
EB01.SuperClean.v2.0.Stable
The folder will already be date-stamped with the creation date, so I find putting that info in the title a bit redundant.
