Merry Christmas everyone, and to celebrate here is an update with some nice bugs fixed.
RomVault will no longer overwrite unknown (unscanned) files while fixing.
.7z caching does not make multiple cache files any more, and cache fixing .7z files in ToSort now works.
Full report crash bug fixed.
Dats containing zero files now show as green.
And a fun version number to... V3.2.1

This is a small but important bug fix release. I discovered a bug that was preventing RomVault from correctly reading some ZIP files with unicode file name and instead reporting them as bad zip files, this has been fixed in this release.
