To import .ini settings for WinRAR, you can use the ""Create WinRAR.ini file"" command in the ""Import and export"" submenu [1]. Here are the steps to do this:

1. Open WinRAR.
2. Click on ""Options"" in the menu bar.
3. Click on ""Import/Export"" in the drop-down menu.
4. Click on ""Create WinRAR.ini file"" in the submenu.
5. Choose a location to save the WinRAR.ini file.
6. Click on ""Save"".

This will create a new WinRAR.ini file and copy the existing WinRAR settings from the Registry to this file [1].

Alternatively, you can use the command line RAR tool to read the default set of switches from the rar.ini file stored in the RAR program folder [3]. The command to do this is:

rar <command> -cfg-<path_to_ini_file>

Replace `<command>` with the RAR command you want to execute, such as ""a"" for adding files to an archive, and `<path_to_ini_file>` with the path to the rar.ini file you want to use [3].

For example, to add a file to an archive using the settings in the rar.ini file located in the ""C:\Program Files\WinRAR"" folder, you can use the following command:

rar a -cfg-""C:\Program Files\WinRAR\rar.ini"" archive.rar file.txt

This will create an archive named ""archive.rar"" and add the file ""file.txt"" to it using the settings in the rar.ini file [3].
