Important Files And Documents Accidentally Deleted

So today I was cleaning out my computer, deleting and moving around old and useless files and documents, etc. I have one folder that contained a plethora of important documents for work (mostly WordPad .rtf documents that I spent countless hours composing). I have another folder, under the same name, in a different part of my computer, with old, useless stuff in it. When I attempted to delete this file, I accidentally right-clicked on the important file, and hit 'delete.Now, a huge amount of hugely important WordPad documents are gone. I checked my Recycle Bin, and nothing was there (on my computer, deleted files oddly usually dont go to the Recycle Bin). I then looked to see if I had stored backups of anything, and I had backup copies of a grand total of 3 of my documents (leaving easily 100 still gone). I then did the only thing I could think of that could possibly restore my lost files: I did a System Restore (I restored my computer to a checkpoint made at about 8 PM yesterday). They were still not there.
