SOW file? Hahaaa... that's long ago. The installation archives from Descent
1 and 2...
I remember that these archives could be unpacked using ARJ.
Anyway, for DXX-Rebirth installation it would be enough to ask for the D1/D2
directories (after looking in some default locations perhaps) and then either
copy the DXX-Rebirth files over to it or copy over the .HOG, .PIG, and user
(demo, pilot, savegame, mission) files from it to a new directory, together
with the DXX-Rebirth files.
I already had the topic covered in my forum why I prefer ZIP instead of RAR. But even a self-extracting ZIP file would not help to install the data files (as far as I know those thingies).
Self extracting would just replace right-click -> extract to with a dialog.
Also I (may not be for everyone) prefer havin the choice how to install it:
* Install over existing D1/2 installation
or
* Just extracting the Rebirth archive and copy the necessary files (cleaner).
When we come to a later version I will consider an installer, however.
Well, you could store a comment in the archive with instructions. Also, it would help greatly when you make those archives, that you have JUST the files, and not a folder with the files in them. This would greatly reduce any confusion. (You would be suprised how many people have made that mistake that have bitched and moaned on kali.)
