After deleting files, I still have no disk space
1. first moved around 11 GB of video files/iMovie and Premiere project files from the Movies folder to my external hard drive
2. restarted and shut down the computer several times. I expected to get a message having to do with File Vault so I could free up space that way, but no such message appeared and the computer just restarted or turned itself off each time.
3. Emptied the trash, which seems to have freed 440MB.
4. Ran the periodic daily, weekly, monthly system routines in terminal
5. In Disk Utility, Erased free space
6. In Disk Utility, verified disk
7. In Disk Utility, verified file permissions.
I don't know what else to do! I expected moving the video files to free up the disk space and Finder still says I have none. Help?
