Alright:
First, the 'dot' files (.trashes, .library, etc) are just files that Mac OS X puts on the drive. They're invisible in OS X. Similarly, Windows puts files (System Volume Information and Recycling Information) onto
its drives, also invisble when running XP, but visible on OS X.
Maybe I wasn't clear:
We're trying to get it so that the music all runs off of the external drive. So right now, there should be no music on the Dell, everything should be on the external.
From here on out, every time I refer to iTunes on the Dell, I mean the
program, not the folder. Forget Windows Explorer.
Go to edit\prefs\advanced, and uncheck 'keep iTunes folder organizes' and 'copy to iTunes folder when adding to library'.
Now, change the folder listed in the box (use the Browse option) to the external's Music folder. This will ensure that all future music added via iTunes (CDs and the Music Store) goes to that folder.
Now, go back to the external drive, and drag the music into the iTunes
library, within the iTunes application.
If all of your settings are right, it should just add references to the music to the library, with all of the files still sitting on the external where we want them.
Please let me know if it works and/or if there are any more questions.
