What is the difference between .cmu and .png?

Description: The CMU file type is associated with the CMU Window Manager, a system used primarily on Unix-based operating systems for managing the graphical user interface. It originated from Carnegie Mellon University (CMU), contributing to its name. These files typically contain configuration or script information that instructs the window manager on how to organize and display windows, manage themes, or handle user interactions. The CMU Window Manager is known for its flexibility and customization options, allowing users to tailor their graphical environment to their specific needs and preferences.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
