The File Types section (screenshot below) allows you to customize the behavior of Authentic Desktop on a per-file-type basis.
Choose a file type from the File Types list box, and then customize the functions for that particular file type as described below.
Windows Explorer settings
You can define the file type description and MIME-compliant content type used by Windows Explorer and whether Authentic Desktop is to be the default editor for documents of this file type.
Authentic Desktop provides specific intelligent editing features, as well as other features, for different file types. Authentic Desktop sets the features for a particular file type on the basis of the conformance you set in this option. A large number of file types are defined with a default conformance that is appropriate for the file type. We recommend that you do not modify these settings unless you are adding a new file type or deliberately wish to set a file type to another kind of conformance.
This group lets you define the default view to be used for each file type.
This check box lets you set syntax-coloring for particular file types.
Disable automatic validation
This option enables you to disable automatic validation per file type. Automatic validation typically takes place when a file is opened or saved, or when a view is changed.
Save empty elements in short <E/> format
Some applications that use XML documents or output generated from XML documents may have problems understanding the short <Element/> form for empty elements defined in the XML 1.0 Specification. You can instruct Authentic Desktop to save elements in the longer (but also valid) <Element></Element> form.
Add new file extension
Adds a new file type to the File types list. You must then define the settings for this new file type using the other options in this tab.
Delete selected file extension
Deletes the currently selected file type and all its associated settings.
Save and exit
After making the settings, click OK to finish.
