What is a JET file?

A JET file is a settings file used by The Jackbox Party Pack series of video games. It contains JSON- or XML-formatted text that defines settings for a specific Party Pack party game. For example, in The Jackbox Party Pack 2, the game Earwax uses a JET file named EarwaxAudio.jet to retrieve and play audio files.

The Jackbox Party Pack is a series of video games that each include a set of party games. For example, The Jackbox Party Pack 2 includes five party games: Fibbage 2, Earwax, Bidiots, Quiplash XL, and Bomb Corp.

Each Jackbox party game uses unique game data stored in a game-specific sub-directory. For example, Earwax stores its game data in the following directory:

~/​Jackbox Games/​The Jackbox Party Pack 2/​games/​Earwax

Each party game's data includes one or more JET settings files. These files determine, for example, what text and what media files are shown at certain points in the game. All JET files are plain text files, which modders can edit to modify what text, images, and sounds appear in a game.

How to open a JET file

Because JET files are plain text files, you can open and edit them in any text editor, such as Microsoft Notepad or Apple TextEdit. Be careful when editing a JET file, as editing the file incorrectly could cause the associated Jackbox party game to function incorrectly.

Database file created by the Microsoft Joint Engine Technology (JET) Engine; contains a database structure, which includes tables and fields, and table row database entries in the JET format.

More Information

The Microsoft JET Engine is a SQL database engine that was distributed with several different Microsoft applications, including Microsoft Access. However, Microsoft no longer supports JET and has moved to SQL Server. You can still open JET database files by renaming the "jet" file extension to "mdb," which enables the file to be opened by Microsoft Access.
