# Configuration files

The configuration files are searched first in %IDADIR%\cfg, then in %IDAUSR%\cfg.

See documentation about the [IDAUSR](https://docs.hex-rays.com/user-guide/general-concepts/environment-variables) environment variable.

In the configuration files, you can use C,C++ style comments and include files. If no file is found, IDA uses default values. IDA uses the following configuration files:

* IDA.CFG - general config file
* IDAGUI.CFG - graphics mode interface config file
* IDAPYTHON.CFG - configuration file for IDAPython

{% hint style="info" %}
The IDA text UI and its configuration file (`IDATUI.CFG`) were removed starting with IDA 9.2.
