DRV files are driver files for the operating system Microsoft Windows. The primary purpose of the DRV files is to establish and communicate with Windows and hardware devices, for example via PCIe or USB.
The DRV files contain commands and parameters for how the operating system and the connected device should communicate with each other. They are also used when installing driver software.
Since the underlying driver model has changed with the further development, play DRV files on Windows Vista and Windows 7 hardly a role. Drv files are mainly found on Windows 9x, Windows XP and MS-DOS.
In general, you can not simply install DRV files. Either they are copied via a driver installer to the right place or you need the matching inf files, which you can install by context menu (right-click). In both cases, however, include some other files to do so.
When pointing an error message to a missing DRV file, you should copy the corresponding DRV file to Windows / system32. However, it should be noted that DRV files can also contain viruses.

Some programs may be capable only of viewing contents of DRV files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate DRV files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Microsoft Windows applications is not on the list, select "Browse" option in order to manually locate the directory where Microsoft Windows has been installed.
Sometimes problems with opening DRV files may not lie with the application itself, but can arise due to other causes, such as:
