You can set ACDSee as the default program to open a huge variety of file types when you double-click them. To Set File Association Options in ACDSee:

1. In Manage or View mode, click Tools | File Association Settings.
2. In the four format sections, select the checkboxes of the file formats you would like to associate with ACDSee for image formats, RAW formats, media formats, and archive formats.
3. Click Save.
