Jagex cache



The Jagex cache, also known as the RuneScape cache, is a bundle of files downloaded onto a player's computer the first time they load RuneScape. On all Windows versions it is typically located at C:\.jagex_cache_32\runescape and C:\Windows\.jagex_cache_32. It contains models, textures, and maps used in the current client version as well as models and textures for unreleased quests, items, and areas in a compressed form. Its purpose is to allow players to quickly load and play RuneScape. Every time RuneScape is updated, the cache on a player's computer is updated as well to reflect the changes.

Speculation on unreleased items and areas
New unreleased and work in progress models and textures commonly show up in the cache every new game client version. Using third party software players can view the cache in its entirety. There is no way to tell whether a model or texture is planned for a future update, is a work in progress, or is discontinued and will never be released. In spite of this many players choose to decompress the cache in favor of speculation.

Game rules and legality
Use of third party software to access the games cache is legal, although some Jagex moderators in response to questions in game claim that any software used to access any Jagex files is a violation of the terms of service and can see accounts banned from the game. Many users feel that the this is not a direct answer to the unique circumstances surrounding the cache and continue to access it every update and post new findings. Posts made on the official forum regarding the cache are hidden and locked because of outstanding rules on account security and third party software. In spite of all these developments, any videos of the cache or tutorials posted on popular websites such as Youtube remain undisturbed. As of yet no action has been taken against accounts of players known to use third party software to access the game cache.

Trivia

 * A different version of the Dragon pickaxe was found in the cache years before its release. When the Dragon pickaxe was released, the Game Guide entry about its special attack showed this same pickaxe model instead of the real model.
