I need to free up some space on my Ti/400, so I ran OmniDiskSweeper. While I was doing that, it reported three large files at the root of my hard drive: "Norton FS Data", "Norton FS Index", and "Norton FS Volume".
I don't remember running any Norton apps on this machine before, but I guess I might have done it a long time ago. What apps generate these files, and more importantly, are they safe to delete?
