Mac Pro trash won't empty
When I choose Empty Trash, it seems to work and the trash bin appears empty. Then in about 5 seconds, all the files are back in the bin.
Coincidentally, this happens only to 31 files. Anything else I put in the trash bin subsequently will delete when I hit Empty Trash -- but all 31 of the files that were placed there a week ago remain. They are PDFs, JPGs, folder of files, etc.
Am I looking in the wrong place? Are the files in iCloud or somewhere else?
Many thanks for help anyone can give!
