What is a ZMK file?

ZMK files mostly belong to Zen Studio. ZMK files are configuration files used by Zen Studio to store Zen Macro Keybinds for Cronus Zen devices.
These files hold macros that define key-bind actions and command sequences designed for game controllers. They serve as a set of instructions that tell the Cronus Zen device how to emulate input commands during gameplay.

Usage: Stores custom key configuration and macros

Functionality: Automates complex input commands on Cronus Zen devices

Editing: Managed and edited using Zen Studio software

How to open ZMK files

You need a suitable software like Zen Studio to open a ZMK file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ZMK file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ZMK file directly in the browser:. Just drag the file onto this browser window and drop it.

ZMK file format details:

Every file has a defined file format, i.e. how the data is arranged in the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the ZMK files is as follows:

ZMK is not a common file extension and predominantly uses a uniform format. The two most common formats are as follows:

• 85% of all ZMK files start with the bytes MKZEN crucial for this file format. They consist of illegible, cryptic characters. Most of these files are 1.3 KB to 1.4 KB in size. The file type is a fairly new file format. Several words can almost always be found in the files, e.g. 1.0.1-beta.1, MKZEN and AFKPUZ. Such files sometimes refer to apex, wayneo, profile, xbox, beam, playstation, siege and rainbow.
• 7% of all ZMK files use ZIP compression, so several files are combined and compressed into one ZMK file. The included 3 to 3 files have file names such as _FIRMY_1.FBK and _PIM_1.FBK. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. ZMK files can be up to 9 MB in size, but are often around 280 KB - 7 MB.

All other ZMK files (8%) have no consistent format. Often described as settings, legends, warzone, play, accurates, gamer, jbaze, mainn, tagfr, call or plug. If you want to find out what your ZMK file contains, drag and drop it onto this page.
