I know my file was not overwritten. It was on a USB thumb drive. VLC would play it just before I accidentally deleted it.
Recuva put it in a folder on another drive and the size looks the same.
The wizard did not find it when looking for video files, clicked "other" and it was top on the list.
I've done this twice now. It would be nice to know how to recover it as a playable video file.
Thanx.
