Diskdigger

The answer. Go to diskdigger app settings and change the minimum file size (in bytes) that should be displayed in the results. With the default settings files that are too small aren't displayed.

Then I decided to try diskdigger for android on another sd card, which a friend gave me once. I decided to restore mp4 files and the program found so many movies! It's a very useful program when you have accidentally deleted an important file.
