I think I just did something bad to my MacBook. I got a new MBP today and I was trying to figure out how to share my iTunes Music with the new computer. I tried moving the iTunes library to my public folder. When I did that the memory on my Mac went from about 120GB left to about 98GB. (I have about 20GB of music). I'm not sure I even moved the correct file. I moved the file back into my iTunes Folder. But since then, the space left on my hard drive has been dropping..it's now down to 91.45. Does anyone know what I did and how I can fix it?
