So I have the MBA and I'm always a little concerned with HD space. I also have a 2 TB Time Capsule that I use as an external HD. I decided that I wanted to move my iTunes library to the Time Capsule to save some space. I don't have a huge library, only 20 GB or so. I followed all the steps on here, including deleting the original iTunes Media folder from the MBA SSD. I confirmed that iTunes was working with the files on the external, and I emptied the trash. Prior to the move I had 66.31 GB free and after I had 66.32 GB free. Am I doing something wrong here? I had hoped to free up about 20 GB. If anyone has any ideas, I would appreciate it. Thanks!
