Hi! I don't know if this will help, but it's a great tool to find files. Not much can hide from Search Everything. Just start typing in the search bar at the top after it has completed down loading. It just takes a few seconds. Let me know if it finds any thing interesting!! LOL

PS If he thinks that Search Everything will find what he's hiding, it might make him think twice!! LOL
Not going to help in this situation IMO, since it's on an Android smartphone - Search Everything is a Windows application. Don't think it applies here .
