.GRV File Extension

File used by Microsoft Office Groove, a collaboration program used in professional environments; contains account information or a Groove invitation; used for logging into Groove or inviting associates and co-workers to view a document or Web page.

GRV files are stored in an XML format.

NOTE: GRV files were previously used to store Groove tool, template, or workspace information.

A GRV file is a game data archive used by a 3D Groove Engine video game. It contains DLLs and game assets. For example, a GRV file may contain .3GM and .GSC files.

In the late 1990s and the 2000s, The Groove Alliance used the 3D Groove Engine to develop many licensed video games (as well as some original games). Many of these games were hosted on third-party arcade websites, such as NickArcade and Disney.com. Others, such as Mountain Dew Skateboarding, Pringles Pony Express, and Jack Daniel's Real Pool, were one-off games used to advertise a product.

3D Groove Engine games store their assets in GRV archives. These compressed archives contain a game's textures, models, sounds, and other data.

NOTE: GRV files are also referred to as Groove World Files.

You can use QuickBMS (Windows) and an associated .BMS script (linked below) to extract the files a GRV file contains.
