How do I move a tab in Notepad++ to a new window?

Right-click the tab you are working with, and click "Move to New Instance", or to open the file again in a new window, click "Open in New Instance."

You can right click the tab and select move to or open in new instance.

This only works for files that are not dirty (when the tab icon is not red).

Simply Ctrl+Left Mouse click to drag and drop the tab will create a new Notepad++ window instance.

Also, make sure the tab is NOT in RED.

1. Press Alt+F6 to create a new instance.
2. Drag the wanted tab into the new instance with the mouse.
