Files wiped to null

So I was working on a project, but shifting around some packages containing lots of class files. However, some things went way wrong and now half of the files I created (13000 lines of my code, 10000 lines of vorbis), are wiped to null. I was wondering if there was a way to recover the files. I had been making backups daily, but I kept them in my workspace (which caused them to all be wiped null too). I’m probably screwed but I wanted to know if anybody had a way to fix my issue.
Also, I tried the local history but it was empty…

Hope somebody can help…
