A CR3 file is an image created by select Canon digital cameras, such as the EOS M50 and EOS R. It may store uncompressed RAW image data exactly how it was captured by the CCD or compressed RAW (C-RAW) image data depending on the camera setting selected. CR3 files were introduced in 2018 with the release of the Canon EOS M50, replacing .CR2 files.
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.
