the only things in mnt are cdrom and windrive

so that means your flashdrive isn't mounted

in terminal type in "fdisk -l"
as root, that's a dash and little L

do that with usb in computer

it will see usb as sdc1, sdf1, sdb1, etc

then make a mountpoint
"mkdir /mnt/sdxx"
where xx is the flashdrive
like
"mkdir /mnt/sdb1"
then mount it
"mount /dev/sdb1 /mnt/sdb1"
now its mounted and should appear under /mnt in file manager

YOU MUST USE THE UNMOUNT COMMAND before you take the usb out!!
use
"umount /mnt/sdb1"

if you pull the usb out of computer before unmounting it will damage it:(

ok i have /dev/sda: 8029 Mb

then i have
Device boot /dev/sda1

witch one is it

is your usb 8gb?

if so that's it
sda1 is your usb

so to open a root file manager in terminal
become root and
"nautilus"
and then access the usb

ok i got it mounted and transfering the files
i hope its moving them to the usb lol

i get this msg in terminal. (nautilus:6843):Gtk-Critical **: file gtkprogress.c: line 583 (gtk_progress_set_precentage) assertion 'percentage >= 0 && percentage <= 1.0' failed
