I have an iRiver iFP-180t 128mb mp3 player / fm tuner / recorder. I've managed to be able to mount it in Linux. It seems as though I can't copy any files with over 13 characters in their name (and all of my mp3s are neatly catagorized by Artist - Track# - Track Title) to the mp3 player. Is there any way to cut these filenames down to 13 characters (example "Sublime - 01 - Garden Grove.mp3" -> "sublim~01.mp3", which is what is automatically done using Windows Explorer in Windows 98) as I'm uploading them to the mp3 player? Thanks.

depends on how they're uploaded, if it's a standard proto, then it'd be simple to write a script to rename them and upload, otherwise i'd suggest moving all the files you want to a separate vfat partition, mount -tmsdos -oremount the fs then upload them from there
