I have a MacBook Pro that I can't seem to purge some files from. I use TivoTransfer (part of Toast) to bring Tv shows from my DVR to my computer. I currently have 28 gig of shows that I wanted to Trash, and thought I had. I use the "Whatsize" app to see what is on my Mac, and it is telling me the files are still on my computer...even though Spotlight is not finding them. I am lost, and not sure what else to try to do to free up the 28 gigs of space. There is nothing in the trash, and I have done a Secure Empty Trash already. Any ideas?
