What is the difference between .m4v and .uil?

Description: The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.; X-Motif UIL Table (UIL) is a plain text file format used by the User Interface Language (UIL) compiler, which is used for creating user interfaces for the X Window System. This format is used for defining menus, buttons, dialog boxes, and other components of graphical user interfaces. UIL files are written using a set of keywords and parameters that can be used to set up the visual elements of the user interface.
