To open rar archives, you can use the app UnRar.
Unrar integrates into the OS, making it easy to open rar when using the in built exporer. This works like a plugin. With UnRar, you can extract files and folders at once just like Win Rar.
How To Use Unrar:
- Launch the app (UnRar),
- Navigate to the archive directory,
- Click on the archive
- After you click on the archive, you’ll see the contents and their sizes, be it files or folders.
- Press the menu button and select extract (either all or the desired file).
Viewing Rar from the in-built explorer:
When you working with the explorer, just click on the archive and it will be opened with the app.
