I fcked up today.

Okay so i have all my files: movies, music etc. in folder named "Downloads" and today accidently i moved it to another folder, which is in the same Disc ( D ). Now i can't enter the Downloads folder anymore, it says that it's empty, but i didin't delete anything i just moved it to another place. And D disc has the same ammount of free space as before. Any ideas what to do? Any help would be appreciated.
