The portable version with the [IniDir] option allows you to set where the settings are saved to. By default, it creates INI files in the same folder as EmEditor.exe to save settings. To save settings in a different folder, edit the eeUseIni.ini file (located in the same folder as EmEditor.exe) and add the [IniDir] option. Update the eeUseIni.ini file as shown below with a custom path, and ensure it is saved with UTF-16LE encoding (with BOM).

[IniDir]
IniDir=%UserProfile%\EmEditorSettings

This method enables all users on a machine to have the same EmEditor.exe path while maintaining their own individual settings, providing functionality similar to a per-computer installation of EmEditor. Users can save the portable version files to C:\Program Files\EmEditor and use the [IniDir] option to achieve this functionality.
