The .CPL file extension stands for Microsoft’s Windows control Panel applets. These are files that store the configuration and application data of Microsoft’s windows operating system and its control panel. The Control panel contains applets which are configuration setting files for windows.
The Control panel folder on the windows operating system allows the users a Graphical User interface to change the settings and configuration on their PC’s hardware and software. Each of the items in the control panel folder is an applet and is stored using the .CPL files. Third party software can also create their own windows applets using the .CPL file types.
