What's NTSE? Do you mean NTFS?
You need to mount your partiton before being able to access the files on it. Perhaps Fedora has done this for you, so it's wise to check first. Open up a terminal window (if you don't know how, then look in the menus for entries like "Terminal" or "Konsole") and type "mount" (without quotes). If your partition is mounted already, you'll see (amongst others) a line like the following:
/dev/hda1 on /mnt/windows type ntfs (ro).
This is what mine looks like and yours may be different (obviously, yours should have "/dev/hdb1" at the start, for example). If there is a similar line there, you need to change to the directory that your partition is mounted on (here, /mnt/windows) so put that info in your file browser, or from the terminal,
$ cd /mnt/windows
If you get permission denied errors, then you need to become root first (do this with the "su" command and then enter your password. The prompt will change from a $ to a #.
If your partition hasn't been mounted, then mount it with
# mount -t vfat /dev/hdb1 /mnt/windows
if your partition is formatted FAT and
# mount -t ntfs /dev/hdb1 /mnt/windows
if it's formatted NTFS. The last bit of those lines tell you where the partition is being mounted to, so you don't need to use /mnt/windows if you don't want to. Just be sure that the directory you're using exists! Again, the # signifies that you must be root to mount partitions (you don't need to type the #).
If you get "unknown filesystem type 'ntfs'" errors, then you'll need to enable support for NTFS in the kernel, but I think there's a module for Fedora you can download for this (search this forum, it's probably been asked before).
There's a lot to read, but hopefully it helps.
