I'm cleaning out my hard drive and deleting all old files I don't need. I'm not sure if deleting original files will remove them from iTunes or iPhoto. Is I "right click" on a single file in the Trash bin, the option to empty trash comes up. Will that empty all trash or just the one file. I don't want to accidentally delete everything in there before I'm sure I don't need them. So basically? Do you need the original files in random folders on your computer for those same files to continue to exist in iTunes/iPhoto/etc, and is there a way to delete a single item at a time from the Trash bin?
