on ubuntu you must compile it.

use: the histogram function to determine the begin of the deletion process and use it as "AFTER" time
Of course, you need external drive space to save the recovered data.
ext4magic DEVICE -m -a 127??????? -d /FREE/SPACE/FOR/RECOVER
If extundelte can't find these files, no old inode copies of these files available,
so you have to look through the whole file system to find the data blocks,
and so you will find a lot files that you do not need.
ext4magic looking and recover based on the journal data which were written during the deletion.
It's a multistage recover process
* First recover step: similar "extundete --recover-all"
* Second recover step: is not included in any other program
* Third step: works like Photorec but more accurately matched to ext4
For a good result, the journal data of the filesystem should not be overwritten after deletion.
Therefor a good idea immediately after the deletion, umount or
or create a copy of the file system or save the journal data.
