If you mean KRyLack RAR Unlocker, I just tried and it didn't work AT ALL (so dumb it even said it doesn't support RAR files:/)... Currently trying with RAR Password Unlocker... It's a RAR containing important things, basically EVERYTHING that has my personal information (including activation keys I own, personal stuff, etc.). I put them all there with a password just to avoid data theft if anything happened.
