I might be wrong, but can't WinRAR open archives even if they're password protected? I believe you could see what files there are inside, but you couldn't extract/open then unless you had the password.

I'd try an open sourced free ware that scans your entire hard disk for your wallet. Docfetcher (http://docfetcher.sourceforge.net/en/index.html) is what I found to be open source, or you can try using 7Zip or WinRAR to try scanning your drives for the file (https://superuser.com/questions/326737/how-do-i-search-the-content-of-7-zip-archives-7z).


Meanwhile, try remembering where the memory stick is by reversing events (just take it logically and try to remember what you thought about hiding it at the time, maybe you'll remember?). What do you mean by 'email account locked'?
