.UI File Extension

There is only one file type that uses the .UI extension:

User Interface File

User Interface File

Stores the user interface configuration for a program; saved in an XML format and contains definitions of Qt widgets with slots and signals; can be viewed in a basic text editor or opened with a UI designer program.

UI files can be created using Qt Designer and Qt Creator, which are part of the Qt SDK.

NOTE: Qt SDK was previously developed by Nokia before Digia acquired the software.
