I could be wrong, but it's my understanding that the files don't go anywhere (unless you've used a "shredder", which overwrites the files with random data immediately). It's just that the paths to access them via normal channels are removed, and the space they occupy is no longer reserved, meaning that other data is free to overwrite the files. You may have been really unlucky and overwritten the files already. Most of the computer expert types on Answerbank seem to be more active during the week (posting from work?), so you may get a better/more accurate explanation and idea for recovery then.
