darkredshift: None of the quotes options worked. Not even the original one you mentioned. Remember, I use Notepad++ to view the GZdoom config, not the command prompt.
is it supposed to be (as typed here):
"GOG Doom"
"Path=<full path>"
Path="<full path>"
GOG"Doom
or GOG""Doom?
I tried all of those and none worked.
Thanks anyway for your help. but I think I'll stick with the Skins option because I know that works. it's inconvenient for the reasons you gave, but I don't really have a choice.
I can always take it out when needed so it doesn't interfere with other WADs.
Probably some misunderstanding, but I was only likening the usage to the command prompt, not talking about viewing the ini with it (I also use Notepad++ as it is a great utility). When dealing with paths that contain spaces it can cause issues with a variety of programs, so I just gave the command prompt as an example of this and how it has to handle the spaces. Whether the same fix would work with GZDoom's ini file paths I don't know (as I use one Doom installation with GZDoom, so I use relative paths (relative to the location of the gzdoom.exe) and no subfolders with spaces).
For the command prompt when setting a variable to a text string that contains spaces it has to be like this format:
"Path=<full path>"
e.g. "Path=E:\GOG Doom\"
However, you said this methodology doesn't work with gzdoom. Just need to check that you did replace the <full path> placeholder with your actual path?
You could try the %20 for the space, but I wouldn't expect that to work. Something else you could try, though, is using the equivalent old DOS path for the folder. It truncates the folder names to 8 characters with no spaces and puts ~1 at the end.
For example, C:\Program Files\ becomes C:\Progra~1\
And E:\My Projects\ becomes E:\MyProj~1\
