I'm confused.

I'm a little confused about how to make a Wolfenstein mod. I know the basics like the import/export feature in Chaos Edit, I know how to make a map, but I just don't know what the proper file directory the mod should be created in. I have the Activision version of Wolf3D. In other words, does the mod have to come from the file directory it was installed? Thanks.

Yes, when you load stuff then save it in ChaosEdit, it overwrites the old files (might give the old files bak extension too, I forgot).

Thanks for the help, I can finally get back to work without any concerns. Thank you.
