Help please - Preventing media from being viewable on Fuze

I believe the Fuze only displays the file if it is a compatible file type. One way to store the files on the Fuze without it being viewable is by using a zip or rar file. Just zip up all the files you want to store and transfer the zip file. Another possible solution is by renaming all the files to some extention the Fuze won’t recognize and then change them back when you transfer it off your Fuze.
