Can I copy files between 2 different iTunes libraries within iTunes?
Direct answers to your questions…


Yes - though that's it's 'masked' address not it's actual location.
Real location is C:\Users\[myName]\Music\
Yes.
You can dupe the library.xml file &amp; change the hard-coded paths to the new location, then import.
Simple, but time-consuming.


Another downside to that method is that once you have separated the identities in such a way, they will remain forever separate &amp; any music added to one will also need to be added to the other.
You will also have to remember to launch with the correct Library every time.

However…
Instead, if you use 'Sync selected playlists, artists, albums &amp; genres you can have completely different selections for each device, even on the same ID.

I have totally different selections on my iPhone &amp; iPod, as I use them for different things.
Might be a whole lot easier to manage.
