I want to know why you moved files to the trash that you don’t want to delete? If you want to save them but remove them from the HD, then put the files in a folder and burn a CD or move them to a flash drive.
Trash is for .....trash. I recommend using the “secure empty trash”., that way the file never comes back to haunt you.
If you read the first three or four lines of the topic, all will be made clear.
