copying iTunes to external hard drive
From the Apple support link could someone clarify what this means:
+"Note: After you click OK, iTunes copies any music files that weren't in the iTunes Music folder, and places the copies in the folder. The original files are left in their original locations. To save space on your hard disk, you might want to delete the original files."+
Does this mean if I delete the original files I will no longer have my current iTunes library (music, movies etc) on my MacBook Pro? I have no wish to do this as I am seeking to simply make a back-up copy of my growing iTunes library.
Thanks in advance for any help with this.
