There are two methods to chose which programs open which file extensions. This first method will change which program always opens the designated file, and the designated file ONLY:

1. Right click on the file and select “Open With > Other”



2. Select the program from the list that you always want that file to open with
3. Click the “Always Open With” checkbox



4. Click “Open”
5. Now whenever you double click on that file, it will always open with the program you specified.

This next method changes the program that opens all files with a matching file extension. For example, if all of your .jpg’s are opening in Photoshop and you want them to open with Preview you would use this method:

1. Right click on the file and select “Get info”



2. Go to the “Open With” section and expand it
3. Select the program you would like to open that file extension with from the drop down list
4. Click the “Change All” button



5. A pop up window will appear, if you’re sure you want to make the change click “Continue”



6. And you’re done! Now all of your files with that extension will open with the program you specified!

So I’ve gone over two different methods, with different purposes: the first method is used for single files, while the second is for all files with a certain extension. I hope this helps eliminate some future headaches for everyone!
