ini file
The ini file is where a user's Zandronum configuration is stored. It is loaded when the game starts, and saved when it exits.
Location
The ini file can be easily found by executing whereisini command in the 
console. This will print out the full path to the ini file in use. On Windows, if the ini file is supposedly is in Program Files, it is likely to be in %LocalAppData%\VirtualStore instead, due to a Windows backwards compatibility measure.
Default locations
- Windows: Zandronum-<username>.ini in the same directory as zandronum.exe
- Linux: $XDG_CONFIG_DIR/zandronum/zandronum.ini (usually ~/.config/zandronum/zandronum.ini)
