One way to get the cabs on the flash drive would be once the flash is inserted, select "external storage" then the backup/export option will appear atop the screen. Hit the button above that option and Bob's your uncle. You'll have to wade thru all your profiles to weed them out but they will be on the flash.
Thanks for putting these up by the way- really looking forward to the cabs! Will be happily sending some dough your way later on.
