Question

I redirected iTunes to an external drive and moved my iTunes library and folder, but my hard drive is still low on space.  How can I be sure that my music is all on the external HD ONLY, especially with the new iCloud technology?  It doesn't look like I created any more space by doing this, AND I totally lost all my iTunes playlists.  I'm not sure if because I added old library materials manually if this messed up my playlists, or if the new location is just not reading my moved library.  In any case, I followed step by step instructions and found a few holes and thought I'd just "figure it out" but I guess I'm not as smart as I thought since I'm still scratching my head many hours later.
Thanks for any support ;-)

Quick answer if you use iTunes' default preferences settings:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Open iTunes and immediately hold down the option (alt) key (shift on Windows) so you get a prompt to select a library, then guide it to the 'iTunes Library.itl' file in the moved iTunes folder.
If this is to a new computer and you put the copied iTunes folder in the default location of Macintosh HD > Users > *User Name* > Music  then you don't even need to start with the option key held down, iTunes will automatically look for it there.  (Make sure there isn't anything already in the iTunes folder there that you want to keep since you will be replacing it with the one you are moving.)
