By default, Notepad++ runs in the single-instance mode. This means that all the files opened in Notepad++ open in the same window. If you open more than one file, then these files are opened in the new tabs inside the same window. This could be a problem if you do not want to open all the files inside the same instance especially if you want to open hundreds of text files.
Fortunately, Notepad++ also supports a multi-instance mode too. We can enable this mode if we want to use Notepad++ in multiple instances. This way we can open all the files in different Notepad++ windows.
Here is how you can enable multi-instance mode for Notepad++ easily:
- Launch Notepad++. Select Settings and then Preferences from the menubar to open Notepad++ preferences.
- In the Notepad++ preferences, select Multi-Instance & Date from the left side list of categories.
- On the right side select the checkbox Always in multi-instance mode and then click on the Close button.
- Close the Notepad++ window and launch it again.
In the multi-instance mode, Notepad++ creates a new window whenever you open a text file in Notepad++ so that it can open that file in that newly created window. This is different from the single-instance-mode behavior where all the newly opened files are opened in a new tab in the already open Notepad++ window. In the multiple instance mode, Notepad++ might consume a little more memory than the single-instance or mono-instance mode.
