there's no way to undelete stuff without a program.... even if you've emptied the recycle bin there's a chance you could get it back, but you're going to need that or a similar program.... a computer never fully deletes anything.... everything you delete is still on the hard disc, until it is over written with other stuff you've deleted... so the longer you wait to try and restore that stuff, the less of a chance you'll be able to do it...
