I deleted a folder that nearly summed up to be 50 GB worth of files. I simply dragged the folder over the trash can. Now, the trash can shows empty (I never emptied it and it never even showed full) and the folder isn't where it used to be. I searched for the folder in Spotlight and it apparently doesn't exist. But my hard drive's memory sure thinks so. I didn't get the 50 GB back. What happened?
