If you installed the program on your computer and downloaded a RAR file from the Internet, you may double click on the RAR file icon to open it in Win RAR, select all files, press the 'Extract To' button, enter a destination path and press 'OK'. It provides complete support for RAR files, so you may both create and unpack them.
You also may associate the tool for PC with archives after installation using the Integration settings dialog double-click or press Enter on the archive name in the WinRAR window. If the tool was associated with archives during installation (the default installation option), an archive will be opened in the program. This may be achieved in one of several ways: double-click or press Enter on the archive name in the Windows shell (Explorer or Desktop). In order to extract a file using Win RAR in the shell mode, you must first open the required archive in the app.
