Sansa Fuze+ Firmware 02.36.03

I know this is a dumb question but what is the root directory that I drop the firmware into is it in the same place you put music, video ,ect.?  I’m not a computer wiz so any help would be great, thanks.

Any way I’ve had me fuze+ for about a day and love it, the SQ is a nice step up from what I’ve had.
