Oh no, that is so terrible!

But perhaps, you have a chance to retrieve your documents. I'm not a computer genius, but I think the files are still on the drive, it's just that they can now get overwritten. As long as you haven't formatted the hard drive or stored files on it that are as big as the capacity, you can access them again.

There are several ways, one of which is even offered by Windows.

But before trying something you aren't sure about, you should read about it and consult a friend with computer knowledge.

I hope, you'll get your data back..
