a part of out homework assignment is to recover deleted files from the partition with the ext4 file system.
I've tried using the extundelete tool, by following this tutorial. The tool recovered a lot of files, which couldn't be opened, so I guess this doesn't do me any good.
Is there any other tool I could try, to recover the deleted files, or is this tool the best there is? I didn't write anything to the partition, before the recovery process, and I recovered the files to another partition.
