Recovering a accidently deleted file in Ubuntu

I’m using ubuntu 9.10 and accidently deleted a specific file within a directory on my system. I checked in the Trash bin and could not locate the file. I deleted it 10mins ago, are there any tools available that I can recovery this file? It’s a really important file.

Any help would be highly appreciated

My partition is ext4

Solution:

There’s nothing reliable.  extundelete runs through the raw filesystem, and restores things that look like files to a recovered file directory.  It’s for ext3, but its creators claim some success with ext4.

The risk is that your file gets overwritten by later writes, so that there is nothing to recover.  Or that the program is defated by some quirk of ext4fs.
