Configuration file

This article is a stub. Please help the ZDoom Wiki by adding to it.

The configuration file used by ZDoom and GZDoom is an INI file that contains configuration settings for ZDoom/GZDoom. It is frequently referred to as just zdoom.ini/gzdoom.ini or the ini file when the context is clear.

The -config command line parameter lets you use a different configuration file from the one used by default.

Windows

Name

The configuration file is named gzdoom-<username>.ini (or zdoom-<username>.ini for ZDoom) where <username> is the username of the player in their operating system.

Location

ZDoom is a portable application, so its ini file is stored in the game's folder. This is true for GZDoom before 4.9.0 as well.

Starting with 4.9.0 GZDoom comes in portable and non-portable variants, which affect where the ini file is stored:

• Portable: same as ZDoom, the ini is stored in GZDoom's folder.
• Non-portable: the ini is placed in Documents/My Games/GZDoom by default. A portable ini can be created forcefully, by first creating a file called gzdoom_portable.ini in GZDoom's folder. If you still have an old INI in your folder, GZDoom will ask what to do with it, you can either move it to the user folder or convert to a portable install.

This was done to bring handling in line with current guidelines and to make it easier for commercial games that often get installed into a folder without write access.

The .ini extension may be hidden if the default setting of letting the Explorer hide known file extensions is kept.

Linux

The default location of the configuration file is /home/<user>/.config/zdoom/zdoom.ini.
