Save not adding file extension in Notepad++? Steps to change the default save extension.

You might have encountered this Notepad++ issue while saving any file with some extension. If you try to save a text file in the new releases of Notepad++, you might end up saving a text file as a file without extension by default.

E.g. Notes.txt might get saved as Notes with “.txt” extension missing.

If you want to save them as .txt by default without giving any extension explicitly, you can override the default extension mentioned in the Save window.


  • Search for Notepad++ by pressing the Windows button
  • Right-click on Notepad++ and Run as administrator
Notepad++ Run as administrator
  • Navigate to the path Settings -> Preferences -> Default Directory
  • Uncheck the “Use new style dialog(without file extension feature & Unix style path capacity)”
Notepad++ preferences default directory

Once you make this change in the Notepad++ preference, the Save As dialog will have .txt extension by default as shown below

I hope it fixed the extension issue while saving in Notepad++.
