After Alan converted his entire library to M4A, I wanted to see how much space that would save me. Unfortunately, iTunes doesn't provide a built in method to do that, and I didn't feel like using a calculator. So, I wrote a java program to parse the XML file that iTunes writes its library to and do the math for me. I can't say for sure that it works, but it probably does. Apparently, I'll save seven gigs by recoding! I might just do it at that rate. If anyone else wants to use it, go ahead. All you need to do is download the file below, then edit the .bat file to include the path to your iTunes Music Library.xml file. Leave me a comment if you have a problem or an idea. Also, this code reads all the songs in your library into Java objects. If you can think of any other neat things I could do with this ability, drop me a comment.
