It sounds like you could have serious disk directory problems. Check the disk w/ Disk First Aid. What does that report?

I'm still not clear on what the problem is exactly. Is the file in the trash and you can't empty the trash? Can you drag it back out of the trash? Or you can't move the file to the trash in the first place? What is the file's name? If you can remove it from the trash, can you rename the file?

As far as asking your Tech guy, unless it's obvious from the file's name that it's something "non-work related" couldn't you just say you had a file (any file--"generic_image.jpg", for example) and you tried to delete it and you got these errors? Who cares where it came from?

Sorry, I don't mean to tell you to lie, but...

Hope this helps....
