How to Move the iTunes Music Files to a Different Hard Disk/Folder?

Moving the iTunes Music Files to a Different Hard Disk/Folder

If you are low on disk space in your iTunes folder then you can move these music files to another hard drive and keep your music library in tact without the need to create your music library again.
If you want to transfer your iTunes to an external USB hard drive, make sure that it is powered up and connected to your computer before opening iTunes.
Opened iTunes, click Edit and then Preferences. Click the Advanced tab.
Make sure the Keep iTunes Media folder organized checkbox is checked, and click Change.

Then select the location where you would like to move your files to. Click Select the Hard Drive and Folder or OK once you?re done.

The files will not move into their new positions by themselves ?To do this ? click File, Library and Organize Library. Check Consolidate Files.

When this process has been completed, go to the new location of your iTunes media and check the music files to see if they have migrated across correctly. Also play one or more tunes to test the music files.
The redundant iTunes music files can now be deleted from the original iTune location (C:\Documents and Settings\?..?\My Documents\My Music\iTunes). Delete everything from iTunes there except files titlediTunes Library.itl and iTunes Music Library.xml. These are still needed.
