I tried burning some files to a 4.38 GB disc, but at 2.88 GB filled, a notification said I only had 60 MB left. I started over again, to make sure I wasn't mistaken, but the same problem occurred. I also noticed that under ''files waiting to be burned'', a file called something like desktopsettings.ini was there. Why would it be there? I may still have a virus, could this be the virus making sure I don't get anything off my computer cleanly? What explains this GB+ of unaccounted room being taken up? Windows 7 64bit system.
