Fantastic App
This app does exactly what it says. It makes finding lost files a minor exercise. Of course the more you know abour the file (date added, date created, etc. or a rnge of days, etc. ) makes it easier, but just the name or a part of the name enables a find. One can also serch hidden system files by selecting that option. Use caution when accessing a system file however.
