This page lets you configure what happens when you push the Win+E hotkey.
This page is only shown on Windows 10 and above, and where Explorer Replacement is available (a normal installation or a portable install with Explorer Replacement enabled in the portable .ini file.)
The Win+E hotkey is what many people are used to using to open a new File Explorer window. When using Opus instead of Explorer, you'll probably want the hotkey to open Opus instead.
The options below let you configure what happens when you push the hotkey:
On earlier versions of Windows, we do not have as much control over the Win + E hotkey and it will typically cause the This PC to open in the default file manager, which will be Opus if it is set to replace Explorer.
If you wish to customize what Win+E does on earlier versions of Windows, try creating a System-Wide Hotkey which overrides the standard one. (Note that if you set up a hotkey that way on Windows 10, it may override the settings on this Preferences page. Only use one method or the other.)
