When I send music through iChat, I usually just highlight a song in iTunes and drag it into the box of a chat where you would normally type, and send it. Every now and then I hear the sound that is made when a file is copied to another location. Are the files I send being copied to another folder? How can i locate this folder so I can clear up space? I must have been sending and receiving gigabytes of files, so I would like to clear up space, especially since I am losing space I cannot account for. Also, is Onyx a safe program to use? I used it once and my computer actually felt like it was going a little faster and I freed up a lot of space.
