Q: Consolidating itunes once iTunes is moved to an external drive

Hi there,

I am hoping somebody will be able to advise me. I followed the instructions on this video:

to move my iTunes folder to an external hard drive so that I can free up space on my internal hard drive. I have also told iTunes in Preferences to look for the iTunes Media Folder location on my external hard drive:

Volumes/MacBook Air Backup Drive/iTunes/iTunes Media

iTunes now works when my external drive is connected to my laptop (and doesn't work if my external drive is *not* connected); all that is fine. I have now saved space on my internal drive by deleting the iTunes folder that was on my internal hard drive.

However, my Q is:

When I consolidate files in "Organise Library"-does this get saved onto my *internal* hard drive, and if yes, does it take up space? Does it matter that my iTunes library is now located on my *external* hard drive?

I'm not sure how consolidating will work now that my library is on my external drive, or does this not matter? Can I consolidate on my external hard drive or am I missing the point as to what consolidating means/does?

Many thanks!
