Answer: To transfer music from iTunes library to another computer, you have two easy ways to be followed.
As you know, if you download or purchase music, videos, audiobook and more from iTunes, iTunes will save them on the iTunes folder on your computer. Thus, to transfer iTunes Library to another computer, you can plug into an external hard drive or a usb flash drive to the computer, and then, copy the iTunes folder to it.
Firstly, Find the iTunes folder on the computer. In Windows 7, the iTunes folder is saved here: C: UsersAdministratorMusiciTunes. If your computer running Windows XP, Vista or other, you can go and find the iTunes folder in the similar save path.
Secondly, download and install iTunes on another computer. Navigate to the save path of iTunes folder on this computer.
Step 1. Install and launch the program
Install and launch this iTunes transfer tool - Wondershare TunesGo on your old computer. Then, connect your iPhone, iPad or iPod to the old computer via a USB cable. This program will detect your iPhone, iPad or iPod as soon as it's connected. Then, your iPhone, iPad or iPod will be shown in the primary window.
Step 2. Copy itunes music from the old computer to iPhone/iPad/iPod
Go to "Playlist" in the left column. Then, the playlist window shows up on the right. Click the triangle under "Add" to bring up a drop-down list. Choose "Add iTunes Playlists".
By default, all playlists are checked. If you want some of them, uncheck your unwanted playlists. Then, click "OK". This program begins to copy itunes playlists with ratings, play counts and skips, etc to your iPhone/iPod/iPad.
Step 3. Transfer itunes music to another computer
Then, plug out the USB cable coming with your iPod/iPad/iPhone and plug it into another computer to make a connection between the computer and your iPhone/iPod/iPad. Install and run this program on this new computer.
Click "Playlist" to reveal the playlist window. Select your wanted playlists imported just now and then click "Export to".
