It is probably more easily done than reading them from windows.
First you should enable fat and/or ntfs in your kernel or make sure it is already there.
Then mount your device (in this example hda, the first harddrive 4th partition) to the selected mount point in your system. example:
# mount /dev/hda4 /mnt/windows/
then you can read files from /mnt/windows/ like it was your ~ directory.
If you want to permanently have it mount at boot, you can edit /etc/fstab
***If your using NTFS you wont be able to write to your windows partition because NTFS write support is unstable. If you change the size of exiting files it can corrupt your entire NTFS system. But reading them works fine so mount it ro (read only)
