I am trying to write an automated installer module that patches the dir
file to add an additional link to a file jtw-manual.info.  My installer module 
complains about not being able to save the file "dir".

If there is no way to change the file "dir" then my system will be less usable 
to users of GNU Emacs on Windows systems.   Everything works fine under Linux, 
although the user has to be in logged in as root to patch the "dir" file, among
other things.

I thought that there must be a way of writing to the "dir" file...

It is possible under GNU/Linux to change the "dir" file.  That may be some way 
forward here.  The user could boot into Linux and run the installer script which
enables them to access the C:/Program Files (x86)/ folder.

Do different flavours of GNU/Linux have the same format for accessing the C 
drive? On my system it is located at /media/www/C1TB where C1TB is the Windows 
name for my C drive.
