Here are the steps:

Part 1: Locating and consolidating the iTunes Media folder

Locating and consolidating your media will make sure all of your content is in the same location. To determine the location of your iTunes Media folder:

  1. Open iTunes Preferences: Mac: Choose iTunes > Preferences. Windows: Choose Edit > Preferences.
  2. Click Advanced and note the location of your iTunes Media folder.
  3. If you’re not going to be able to complete these steps all at once, it’s a good idea to make sure that any new content you might add to your iTunes library gets added to the iTunes Music folder. To do this, just be sure there’s a check in the checkbox next to “Copy files to iTunes Media folder when adding to library.”
  4. Click OK.
  5. For iTunes 9 or later, choose File > Library > Organize Library… > Consolidate Files.     For iTunes 8.2.1 or earlier, choose File > Library > Consolidate.
  6. An alert may appear stating: “Consolidating your  library will copy all of your music into the iTunes Media folder. This  cannot be undone.”Note:

    Mac OS X: By default, iTunes on  Mac OS X keeps a consolidated library, so this option likely will not  increase the space needed on your hard disk. Windows: Consolidating will cause iTunes to copy all of your music files that appear in iTunes to one central location on your computer  (the iTunes Media folder). The original files will now be duplicates  which you will need to manually remove from their various locations if  you don’t want them to take up additional drive space. If your computer  does not have enough hard-drive space, this process will not work  correctly. Contact your computer manufacturer or Microsoft for  more information on how to obtain more space to perform this action.

  7. Click Consolidate.

 

Now you can remove the old folder after you validate everything has moved over. Get your hard-drive space back for some more torrenting!
