In short, I need to undelete a few hundred photos from about 700GB deleted data, and manually scrolling through the output takes forever. There is a Find option in Terminal, but it only works within the visible screen. If I select all and copy to some text editor, it only copies the visible screen. So how do I find the one little folder that I need to undelete?

Sorry for the lame question, but I'm really at my wits' end >.<
Using Xubuntu 13.04, the hard drive is fully functional, I just deleted the wrong data.
