I've recently brought my macbook pro and put many songs on it from my older computer with a usb drive. I added these to itunes. When I search the song in finder I have 2 copies of the song, I have one in the itunes folder and one in my regular music folder. Does my computer make 2 copies of the song and does this take up twice the space? ( I'm figuring it does take up twice the space because when I check the memory I have about 16 gig using music when I have about 8 in my itunes) .. Also when I download songs from the internet it also makes two copies, Is there any way so it doesn't make two copies of the songs because this is frustrating me and i'm fearing it does take up twice the space and I can't figure out what to do about this... Thanks
