I have just deleted a scanned pdf file.
I'm trying to recover it with
The problem is that scalpel will recover many deleted files and names them numerically (e.g. 0001.pdf, 0002.pdf, ... 9999.pdf).

some text in the deleted file.
The problem is, that the file is scanned (I know the original file name), so I don't know what to search for.
