Notepad++ open file in a new window
As you might have noticed, Notepad++ doesn’t offer the option to open a new window, and opens all files in the same one.
In order to open a new window, in which you’ll be allowed to open files / create new tabs / drag and drop opened files, simply put your cursor on the tab name of the file you want to open in a new window, click and keep the mouse button pressed, drag the mouse out of the Notepad++ window, release the mouse button – and voilà !
It is now opened in a new window.
Take care, it does not allow to open unsaved files in a new window. You’ll have to save them first, or move them to a second window already opened with an existing file.
