I assume you have the NTFS drive mounted in the computer and are
dual-booting from it. If so, here's how I do it. As root create a
windows directory under / Then from the CLI type "mount /dev/HDD"
<Enter> where HDD is the actual name of the device. On my computer
it's sda1. You can then move files, etc with your file manager. To
unmount - as root "umount /dev/HDD"

You can always do "man mount" and read the documentation
