as their is no file that says files of type. just datafiles but that doesn't lead to anything.
Hmm... Are you using Vista or Windows7 ??
Because they hide some folders and files, and won't let you alter or find them most of the time.
If so, do a quick "Change of Installation" (you won't lose any files/data, it just moves it out of the troublesome 'Program Files')
Open your C: drive and create a new folder and name it Bethesda. Then copy the entire Morrowind folder from the default position and install it in the new folder you just created.
Example: default folder: C:/Program Files/Bethesda
New folder location: C:/Bethseda
On a Vista/Win7 computer, moving out of Program Files will help with many problems associated with using mods & patches, and using the CS.
And thank-you for understanding that I'm trying to help. I'm just giving advice when I think it needs to be given.
We all start at the beginning, and getting help is part of the learning process.
I never would have finished my mods without the community here.
