Use this tip when a file opens in the wrong application. For example, if I want a jpg file to open in Adobe Photoshop Elements instead of Preview.
Click on the file, hold, and drag the file to the icon in the dock that corresponds with the application you’d like to use to open the file.
With that said, here would be a solution to my example above: instead of double-clicking my jpg file and it opening in Preview, I should click on the file and drag it to Adobe Photoshop Elements so I can manipulate the file.
