Single Answer Multiple Choice
Which file name extension is directly associated with the Control Panel applet?
The icons in Control Panel are associated with files that have a .CPL file name extension. For example, Sysdm.cpl file is associated with the System applet, and the Desk.cpl file is associated with the Display Properties dialog box. By default, the .CPL files are located in the System folder or the System32 folder, depending on your operating system.
If a .CPL file becomes corrupted or damaged, then you may get an error message such as Explorer caused an invalid page fault in module KERNEL32.DLL at xxxx:xxxxxxxx error. If a .CPL file is missing, either the icon will be missing in Control Panel or the icon will be present but nothing happens when you double-click it.
Files with a .BAT file name extension are known as batch files. A batch file is a text file that contains one or more commands to the operating system.
Files with a .DLL file name extension are known as dynamic link libraries. A dynamic link library is a collection of small programs that can be called by another program. Dynamic link libraries contain functions and data. When they are used as device drivers, they have a file name extension of .DRV.
Files with an .EXE file name extension are known as executable files. An executable file is a program that, when opened, instructs the operating system to run the executable’s program.
Control Panel is a tool that manages all devices, including driver installation, device property management, and program installation and removal.
