My iTunes library is currently a pig stye. It appears that I have three different directories that iTunes was reading from and I believe that was causing iTunes to run slow. I purchased an external HD to house my library temporarily and used iTunes to consolidate my library there a few days ago. I also have all the old iTunes folders still on my iMac HD. I guess I have a two fold question. First of all it doesn't matter that the hard drive that I just consolidated my library to is formatted as Fat32 if I plan on returning it to my iMac HD? This is where I get confused and brings me to my next question. iTunes says my library is 276.84GB. The external HD where I have my iTunes library says that I'm using 289.12GB. What's with the discrepancy in size? When I check the sizes of the folders where my iTunes library used to reside I get the following numbers: /Music/iTunes/iTunes Music - 181.75GB /Music/windows - 168.78GB /Music/Library - 37.33GB If I add those up I get 387.86GB. What does that mean if it's off by 111.02? The only reason I'm worried about this is because I've spent years tagging and adding album artwork to my library and I would hate to see some of that go to waste.
