Find a better tool: j2recover
which can be downloaded: j2recoverlist
Didn't work for me.
Thanks for your comment.
Could you check lost+found?
The restored file should be /cg/lost+found/10.
Sorry my mistake.
Hmm, just tried again. File is restored to lost+found but it is
Another situation that j2restore will restore an empty file is:
the disk block was reused by other file after deletion.
