Find original filename after Data Rescue recovery

Solution 1:

Data rescue is fairly sophisticated program on the Mac. If there were any traces the filename in the filesystem, that software puts the file name back when it performs a simple undelete. What you are seeing are video fragments of files that were found on the filesystem totally detached from a directory entry.

In short you're not going to be able to get the file names back without a backup or other source of the file names.

Hopefully, those AVI files are actually complete files and not just fragments of video content that it managed patch together with a proper header and a sequentially made-up filename.
