How to keep track of files added to internal mem vs. memory card?

[kpl]

Hi,

I recently got an 8GB card for my 8GB Clip+. The internal memory is nearly full and I want to load more music onto my new card.

I'm a linux (Ubuntu) user running the clip in MSC mode.

Has anyone thought of a clever way to keep track of what music has been added to the internal memory? I don't want to start going through my library adding my 'favorite stuff' to the card, only to discover I now have a duplicate on the device. Simply, I don't want to add any song twice, but can't think of a simple way to check what I have loaded already without methodically checking, song by song, artist by artist.

I suppose one alternative is to delete all music from the player, then add what I want in one 'session,' so I can remember what is on there already.

Sometimes I load music using Rhythmbox, and other times I just drag and drop.

Open to ideas!

Cheers,

K
