Er,well...It may be not a problem.
It just don't look perfect.
well,if I just delete many files on the disk,then I wipe the disk.
Later,I misdelete a file,then I want use FinalDate to recover it,but I see many named 'zzzz.zzz' on the list.
It will take some time to find the correct filename,and it don't look clean.That's what I think.
