Your firmware version should be in Settings/System Settings/Info on the Fuze.
What I mean by the zip file is that when you go to this post:
http://forums.sandisk.com/t5/Fuze/Sansa-Fuze-Firmware-Update-01-02-31-amp-02-03-33/td-p/139175
and download a file, it arrives as a .zip file, which is a file made to be sent online as a complete package–in this case, a folder with the firmware update inside. When you get it, you right-click on it and your computer asks if you want to Extract (or unzip) the files. SanDisk doesn’t tell people that the actual firmware update is FuzeA.bin, and some people on this forum have tried to just put the zipped file onto the Fuze, which doesn’t know what to do with it.
