Opening FUK Files
The FUK file type is primarily associated with Euro Truck Simulator 2 / Unreal Engine.
What is a FUK file?
FUK files mostly belong to Euro Truck Simulator 2 / Unreal Engine. The FUK file is a specialized game data file.
It is used primarily by Euro Truck Simulator 2 to store binary assets such as vehicle configurations, environment details, and other in‐game data.
In addition, some files with a FUK extension are used in games based on the Unreal Engine, like Postal 3, to hold map and level design information.
These files are not meant to be opened with standard text editors due to their binary format. You need to use the game itself or modding tools specifically designed for these formats. For Euro Truck Simulator 2 details, visit the official website. FilExt.com note: This format remains proprietary, functioning solely within its dedicated game environments.

FUK file format:
If you know the file format, you can also find out how to open or edit the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. File extension, signature and file format must match; otherwise errors will occur when the file is opened. If there are problems opening a file, you must first determine the file format used. Our evaluation of the FUK files is as follows:
The FUK file extension is not widely used. Such a file is primarily used by a single program. However, the following two file formats are common:
- 80% of all FUK files start with the bytes xV4, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The file size is in the range of 230 KB to 2 GB. It is a modern file type. An example of a file name is data1.fuk or data0.fuk. Such files sometimes refer to patch.
- 15% of all FUK files are based on the popular Unreal file format. This Unreal Engine Package by Epic Games may contain textures, maps, music files, 3D models, or game settings. The package can be created and edited using the Unreal Development Kit. These are binary files, so they do not contain words or text. The files are on average 8 MB in size and range from 320 KB to 9 MB. Several words can almost always be found in the files, e.g. Level, None, PhysicsVolume, PointRegion, Vector, Zone, bNetDirty, iLeaf and Location. A common filename is Church.fuk. Such FUK files store data about suburbs, east and mall.
The remaining 5% of all FUK files are files with no common format. Just click the "Choose your .fuk file to analyze" button on this page to find out what your FUK file is.
