Clearing Deleted Voice Recordings from Database

I have a sanza fuze 4Gb, and have MSC mode selected. To remove mtable.sys did not work. The recordings I have deleted from Windows still show in the player (but they are very fast to play - because they don’t exist on the player.) It would be great to have a choice “Update database” in the Voice menu, or that the inititalization at start-up actually checked which recording files there are in Voice.
