How can you tell how much space is taken by checked items?

Question

I have a large iTunes library (over 270 gb) and managed what goes onto my 160 gb iPod using the checked items.  It took me a long time to get it right and I would make changes (unchecking items) to accomodate new songs as I loaded them.  Somehow recently I managed to lose that information so that now everything is checked and I need to start all over.  So two questions:
Is there anyway to "recover" what had been checked/unchecked at a given point in time?
And, what would be most useful, is there anyway to track the amount of space taken by checked items?
As to the last question, currently at the bottom is a status bar that tells you how many items, how much space and how many (days/hours) are taken by the full library.  It would be incredibly useful if that status bar also included the same information for checked items.  It would make it so much easier to manage the iTunes library content.

Answer 1

As above use playlists. If you really need to recover the checked/unchecked status from earlier in time then I have a script that can be tweaked to do this called ExportImport, as long as earlier in time is the last time your library database got archived into the Previous iTunes Libraries folder. It is currently set up to export and then import playcounts, but adapting it to do Checked would be quite easy.
