If you click on a file and the wrong app opens it, you can change the default application to open that file or file type. These are the steps to both change the default app to open one specific file or to change the default app to open all files of one file type.

Right-click the PDF, choose Open With Choose default program or another app in. Choose Adobe Acrobat Reader DC or Adobe Acrobat DC in the list of programs, and then do one of the following: (Windows 10) Select Always use this app to open.pdf files. (Windows 7 and earlier) Select Always use the selected program to open this kind of file. If you want to change a default app other than your browser or email client then you can still do so. Open up Finder, navigate to the file in question and right-click it to bring up the contextual.

I frequently work with images on my MPR. Typically I just want to view an image instead of edit it so having Preview as my default app makes sense.

However, some images I know I am going to edit and edit and edit. By changing the default application to photoshop for that file, I can save a bunch of time.

Anyway, here is how to do it for one specific file only first. Below I’ll show you how to change the default application for all files of one file type.

Change Default App for One File:

1. Ctrl-click on the file you want to open
2. Click Open with
3. Select Other

4. Select the applcation you want to open the file
5. Select Always Open With
6. Click Open button

If you want to change the default app that opens all the files of one particular file type, you can do that too.
