Yes, my computer's working — but I need my files!

So I've got my computer up and running yet again… but my irreplaceable files are well at least temporarily lost. I'm trying to recover them but it's going to take forever… *sighs* and to think that the problem with the computer was actually just a simple one. At least the computer is running nice and smoothly now. I just have to make sure not to crash it while I wait for the program to go and find all the files and then sort through the mess and figure out what I wanna keep… if any of it is actually salvagable.
