How to Undelete Files from ext3/ext4 partition

The first step should be to stop all writing processes on the related partition and unmount that partition as soon as possible. Now you have the choice: if your partition uses ext4 you have to use extundelete, if it’s ext3 you can use also ext3grep. Personally, I prefer extundelete, since it supports both file systems and seems on one hand much faster to me than ext3grep and it’s also easier to use on the other hand. Due to that, the following examples are for extundelete (you can find a ext3grep How-To here).
If you know the path and the name of the file (let’s assume it’s /home/tux/cv.tex and /dev/sda4 is mounted to /home) you deleted, switch to root and go to a partition with enough free space to store the deleted files. Then:
# extundelete need the relative file path
me:/tmp # extundelete –restore-file tux/cv.tex /dev/sda4
As soon as extundelete finished, you’ll find the recovered file in /tmp/RECOVERED_FILES/tux/ .
If you deleted more than one file in a directory or a directory itself, you can use –restore-directory :
# extundelete need the relative dir path
me:/tmp # extundelete –restore-directory tux/Documents/tex/ /dev/sda4
There are some more useful options as –restore-all , –restore-files, –after ‘dtime’ or –before ‘dtime’, but in the most cases the two examples above should be enough. You can find both tools in my buildservice repository.
