  4. Try a saved PDF

    Open File Explorer and double-click a PDF. It should open in the app you chose.

Check your result

  • The saved PDF opens in your chosen app. Its filename, pages and contents are unchanged.
If you need more help

Open one file in a different app

Right-click a saved PDF, choose Open with and select another installed app. Use this when you only want to open that file differently.

The PDF icon changed. Did my file change?

An app icon can change when its default changes. That does not turn a PDF into a Word document or web page. Show file name extensions to check that the filename still ends in .pdf.
