Bill, I also use 250 Meg jump drives for the same reason you use them. I do have a couple of 2 gig drives that contain my entire library of books that I almost never use for playing. They are for those rare occasions that I am looking for a song that is not on the drive I use for playing.

You do not need either of the files that came with the Cruzer. And, you will gain some space by deleting them.

You can see how much of your jump drive is used by going to My Computer, then using the right mouse button click on the drive. Then click on Properties. You will get a pie shaped display that shows how much of the drive is used. You will probably be surprised at how much space is available. At 350K per chart you should get over 650 songs on a 250Meg drive.
