What is .sys file extension?

Developed by Microsoft, the SYS file format was designed to store compiled system resources like configuration variables and settings required by Windows and DOS (Disk Operating System) for performing its intended operations. Also known as Windows system files, the content of a SYS file normally consists of core Windows and DOS components like driver resources and references to corresponding Dynamic Link Library (DLL) modules. The io.sys file, for example, contains DOS initialization code and driver resources required by DOS, while the config.sys file stores system variables and configuration settings of Windows and DOS. The content of these SYS files can be viewed or edited by using applications that have been built into Microsoft Windows.
