Hi - There is an avi file I found on my computer of an ex gf of mine. Now that I have a NEW gf, it would definitely not be a good idea to keep it on the computer. Problem is, I can't seem to delete it. I'm not super tech savvy, but I was able to delete quite a few other files with no issue, this is the only one that remains. I tried to hold option down while I emptied the trash, as I'd found that online. No go. Help? Thanks.
