Files with the file extension DRV are associated with multiple programs and applications. The most common association is a Device Driver, but the extension can also be related to a Program Overlay or Diablo. DRV files contain data and information related to the program that created them.
If the file is classified as a Device Driver file, it is a system file type that contains instructions how the specific device should communicate with your operating system. The instructions are commands responsible for ensuring devices on your PC are working properly. DRV files of this type are primarily created in the Windows operating system.
DRV files that are created as a Program Overlay are a data and source code file type that contains programming language which allows you to run programs that exceed the memory on your PC. The process of overlaying involves replacing one set of commands with another to bypass physical memory limitations.
If the file is associated with Diablo, it is a game file type that contains character data for multiple players. Diablo is a game created by Blizzard Entertainment which can use a third party hack application or an emulator to work with DRV files.
How to Open DRV Files
DRV files that are associated with Device Drivers are not designed to be opened by the average PC user. Since the files are related to Dynamic Link Library files which are critical for running your operating system, opening them can accidentally cause modifications which will render a device or program useless. If the DRV file becomes corrupt for any reason, you can enlist the help of someone who understands this file type to delete the file and then download its new version.
DRV files that are Program Overlay files are typically written in plain text. If you are a developer who understands how to work with source code, you can open and view the contents of the file using any text editing program such as Notepad or WordPad for Windows, Apple TextEdit for Mac, or gEdit and Nano Editor for Linux.
If the DRV files are related to Diablo, you can open them using Diablo II Hacks, which are third party programs compatible with Diablo by Blizzard Entertainment. Although Blizzard Entertainment takes a firm stance against using hacks and cheats with their gaming application, die-hard gamers still use these applications to open and edit the contents of a DRV file extension.
The other way you can open DRV game file types is by using a software emulator that is designed to open and play DRV files with a Blizzard Entertainment game. This is the best and safest method for opening DRV files of this type.
