I want to make Master PDF Editor (MPE) the default for opening PDF files. I right-clicked a PDF file, chose Properties > Open With. MPE was not listed. I clicked Show Other Applications but MPE was still not on the list. I tried opening the PDF file with MPE, editing, and then closing it. MPE still did not show up.

So how do I make MPE the default program, or at least appear on the Other Programs or Show Other Programs?

  • Thanks for the answer --> I tried this but still can't see Master PDF Editor under Show Other Applications. I would appreciate any feedback. – user329589 Sep 23 '14 at 4:54

If Master PDF Editor (MPE) is not listed all you need is to create a MasterPdfEditor.desktop file. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

gksudo gedit /usr/share/applications/MasterPdfEditor.desktop

Copy and paste the following, and then save and close the file. (Note that the *.desktop files should be in /usr/share/applications).

[Desktop Entry]
Name=Master PDF Editor
Comment=PDF and XPS files editor
Exec=/opt/master-pdf-editor/master-pdf-editor %f
Categories=PDF Editor;XPS Editor;Office;Utility;Text Editor;


Right click on the PDF file --> Open With --> Open With Other Application

If you don't see Master PDF Editor in the list, click on Show Other Applications

Scroll down to Master PDF Editor, highlight it, and click on Use as Default.

I don't have sufficient reputation to comment on the previous answer, but I would just like to add that for me the file was /usr/share/applications/MasterPdfEditor.desktop NOT mpe.desktop.

If you have MasterPdfEditor.desktop, just edit that. Otherwise, you will create a file called mpe.desktop but it will not be detected by the 'Open with' dialog.


Problem Resolved:

To set the file associations :

Step 1. Right Click on the file

Step 2. Choose Properties

Step 3. Go to the Open With tab.

step 4 Choose your file viewer. For eg. Master Pdf Editor

Now click the button, Set as Default

Now, when you reopen the file/application again, then it will open in your set default application.
