I download the tool you mentioned but I have some questions about the usage.
I try to list out the dir content on my usb flash disk, which is fat
file system.
But I got the below messages:

# mount
/dev/sdc1 on /media/disk type vfat (rw)
# ls /media/disk
ifrename  iwconfig  iwevent  iwgetid  iwlist  iwpriv  iwspy  strace
strace.output  strace.output.tar.bz2
# ./fat-util list strace.output /dev/sdc1
strace.output not found.
#

did I use the wrong cmds or the file system type the utility not support?
appreciate your help,
