Is there a way to automatically open the folder extracted from WinRAR?
Can I also configure WinRAR to open the folder only when I extract from the GUI, and not from the Explorer right-click context menu?
This can be configured in WinRAR with the Display files in Explorer option on the extract dialog, as shown in the screenshot below:
Enabling it will work for the current archive but any further archives extracted will have this option disabled. To ensure it sticks for all archives just click the Save settings button underneath, then it will apply to all archives being extracted in the GUI.
