File extension drv information

A file extension is a set of characters at the end of a filename, which indicate to a computer to which program a file belongs. This tells the computer’s operating system which program should be used to open the file. File extension DRV identifies driver files. A driver file allows the computer to recognize hardware devices attached to it therefore allowing the computer to communicate with the attached devices. Normally, computers automatically identify the drivers associated with new hardware. Thus, there is no need to open the driver files manually.
Drivers depend on the installed hardware and are usually system specific. The hardware installation software for Windows enables it to automatically open file extension DRV files. This is why the files should not be opened automatically or edited. The communications subsystems, to which the hardware is connected allows the driver to communicate with the hardware device. The driver issues commands to the hardware device when a program calls on a routine in the driver. The hardware device then sends data back to the driver, which may cause the occurrence of certain routines in the calling program.
