Notes about the UTD file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The UTD file type is primarily associated with 'BioWare Aurora Engine' by BioWare Corp.. A Door is an object type that serves several functions. When closed, it blocks movement of creatures, and may block line of sight. Additionally, doors may serve as an area transition targets and trap locations. Doors and Placeable objects are stored in the game and toolset using BioWare's Generic File Format (GFF).
