Today Blizzard announced the beginning of the WoD Alpha. This also included an announcement of a new file system for Warlords and future Blizzard games. Say goodbye to the old MPQ (Mo’PaQ, short for Mike O’Brien Pack, named after its creator) file structures. Say hello to CASC (Content Addressable Storage Container)! MPQ files have been in use since around the time of Diablo (the original game) and earlier. It appears that Blizzard’s technologies for game clients have finally exceeded what the MPQ format can handle. Time for Data-miners to learn to crack a new file format!
Here are some of the features offered by the new format:
- File Corruption—File repair tools are a thing of the past. The file structure maintains itself, helping to prevent errors during installation.
- Speed—Real-world game performance should increase for many players thanks to a non-redundant file structure—in layman’s terms, the game can find the assets it’s looking for more quickly.
- Patching—Updating your game files should be faster and more reliable. Patch data is integrated seamlessly, and no longer requires double the installation size on-disk when patching.
- Client Hotfixing—CASC allows us to be able to hotfix client game data, similar to server hotfixes, giving us the ability to address client-side issues that would normally require a patch.
- Streaming—The new format provides better support for streaming data and gives us greater flexibility to define how content updates are delivered and released.
- Expandable—The file structure is built to allow easy integration of new technologies in the future that we haven’t even thought up yet.
- . . . and more!
