This section describes Windows NT 4.0- and Windows 95-style INF files. An INF file is a formatted reference file that contains information about installation files and devices such as filenames, version information, and so on. You can create or modify an INF file using any text editor. If you are providing a Windows NT device driver to be installed with a Control Panel application or other installation program, you must create an INF file. The INF file enables your device to be installed and to work in the Windows NT environment.
