I'm transferred all of my iTunes library (iTunes folder) from my PC to Mac via Ethernet. After the the transfer I noticed I have 457 GB of data in iTunes PC and 491 GB in my iTunes Mac. More data on the mac? What's up with that??

A couple of things come to mind here. I dont know what the disc sizes are, meaning, if say the windows machine was an old xp machine with like a 30 gig drive and the mac is newer and thus has a significantly larger drive (1tb or so) you will get a difference because of the way the file system allocates data.
Also the file systems are different so each file system will write the data differently ( hope I'm saying that right)size will be different this will add up more than you think.

Kinda think of this like when u make a backup onto cd the cd file system is much more efficient, so the file is "tighter" normally than off of your hard drive.

However it does seem like a large gap I would def question it myself if I were in your shoes. Have you compared the two to make certain there are the same number of files in each?

I have seen that there are many people here significantly "smarter" than I hopefully one of them will chime in.

good luck

Thanks for the response! Exactly, what's even more weird is I get about 32,000 files on my PC and about 41,000 on my Mac!? I mean I guess it's safer to have more than less, but doesn't make much sense..
