Outlaw asks the operating system what type files are being used as assets and most often it gets things right.
But sometimes you may have an XML file that you want to open in the editor and instead, Outlaw thinks it’s an audio file and tries to “play” it.
There’s an easy fix for that.
Open Preferences and go to the Advanced pane.
Look for a line with textsfx in the first column. Select the second column of that line and add xml to the end, separated from the others by a comma.
(Note: If you don’t have a line that starts with textsfx, hit the Add New Preference button in the upper-right and add it.)
Now when you double click an XML file in your asset list Outlaw knows to treat it as a text file and will open it in the editor.
You can also set up other suffixes as image files, audio files, etc. Here’s what that part of Preferences looks like in my copy of Outlaw:
Just make sure the options in the second column are separated by commas.
