Considering you are using knoppix cdrom based.
Procedure:
1) open konsole --> type su <enter>
2) type passwd --> type any password you want
3) type mount /dev/hda* /mnt/hda* *what your ntfs partition is.
4) type chroot /mnt/hda*
5) open K menu-->system-->more programs--->File manager-super user mode. It will ask password. Enter the password you just created. You need to change the konqurer settings to file management.
6) Go /mnt/hda* or whatever your mount point is and copy and paste whatever you want.

Hope it will work.
