Missing Memory

I have a Sansa Clip which I had filled up with music.  In order to make space for some new tracks I deleted some of the existing tracks.  However, there appears to be some lost memory.

According to the properties of the two track folders, I have used about 700MB.  However, when I view the entire unit in Explorer, it tells me that I only have 287MB left, and have used 1.6GB.  Where has that gone?  Do I have to reset the whole unit to recover the memory?

I am using the latest firmware.

Any advice appreciated.

What system are you using?  If you use a MAC or Linux, you need to empty trash after deleting or you won’t be able to recover the deleted space.
