I'm done with checking textures, models etc for duplicates, compared to Toadeater dod demo. For example, they are a few terrain textures in Anssi release, which are not in Toadeater demo. In Ben Glover, which i released already, they are terrain textures which are not the same with Anssi. Make a .qrk file if you want with the files that has the same name ,but they are different in content, so you do not have to overwrite other files. If you will find empty folders, is because i didn't delete them, was nothing in them.
In the archive you have .bak file wich is a backup file.
.prt file is a model format it seems, but usualy is made along with the .bsp and you don't need it when you distribute your files.
The .bsp files, can be opened by Quark editor, but the arhitecture (poly) of the .bsp file cannot be modified by Quark.
.map files can be opened and modified in Quark editor.
arghrad.exe is used with Quark for .bsp making of the final level you make, beside other files.
autoexec.cfg and anssi.cfg are other .cfg files.
“bspinfo3.exe = Dumps information on a bsp file.”Quaddicted.com
.ico is a DoD icon file
“demos” folder have .dm2 demo files in it, which can be opened by programs that can see Quake 2 demo files. Or play them by ingame console.
“Instead of placing a downloaded demo in the baseq2/demos folder, and typing 'demoname.dm2' in the console without quotes, Demoplay makes it easier to play demos from any location just by doubbleclicking the .dm2 file. Plus it has playback options like fastforward, pause and slowmotion.“
“dod2” folder has many .map files in it and .mrg files, which can be renamed as .map files and thus opened. Not all renamed files work.
“env” folder contains the day sky .tga and .pcx. Don't modify those, before contacting Alex

“prefabs” folder has .bru files, a sort of files that has many poly's that makes a prefab, a made object if you will, from poly parts. It can be opened by BSP editor. It can not be opened by Quark, only if you save it first as a .map file with BSP editor.
“save” folder has save files, which are made when you save the game.
“scrnshot” folder has screenshots in it from DoD.
