I was downloading a torrent of a game (around 4GB) and since I was going to sleep, I set it to shutdown the computer when the download finished.

I woke up today, excited to see the computer's off and when turn it on, everything's gone.

I opened up FDM and the download is completely gone along with many other ones. Even the folders are empty.

How come it did this?

Now I have to spend a day downloading it again!
