Feature Request - 'Test files' feature/button

Hi, thought it might be handy to have a 'Test files' feature/button to test .7z encrypted files in the encrypted drive/folder (e.g. 7z t -r -pMySecretPassword *.7z).  

I realize that it can take many hours to test a large drive/folder, and it may in fact interfere with the default background scanning and/or a low Interval for full scans/manual Sync files run.
