How do you transer your ipod with old music to a new itunes?

Depending on your iPod, one way to do the transfer is to simply set your computer so hidden files and folders are shown, then to acess your iPod as if it were any other hard drive. So you open it up and somewhere within the iPod will be a folder named something like "music" and within that will be folders marked (I've found) f#.

The only problem is sometimes the encryption used to store the music doesn't convert properly so you get loads of 4 letter songs. The way to deal with that is to right click and sellect settings on the track and change the decryption type.

There are also many programs which will allow you to transfer. Some free, some with a 10 song trial sort of things, some with a purchase fee. But the way I've told you above is easy and normally works well.

the reason i say depends on your iPod is because I've only used this on the 2nd generation iPod, the 4th and the iPod nano and shuffle. haven't used it on the latest touch, nor the latest shuffle and nano.

Hope this helps.
