Extract text from Killing Floor system files (UCL)
To convert UCL system files to another format, you need Killing Floor or other Game software.
To convert other file formats to the "Game Modification Data" file type, you need software like Killing Floor or a similar tool.
A .UCL file is a Killing Floor System File, a proprietary game data format utilized by Tripwire Interactive. It functions as a cache or registry file that allows games built on the Unreal Engine to quickly recognize and load custom modifications - often called "mutators" - without needing to parse every system file on startup.
The main disadvantage of the .UCL format is that it is a strictly proprietary and closed system file. It is entirely dependent on a specific game installation to function. You cannot open it natively on standard operating systems, it is not supported by web browsers, and it has virtually zero utility outside of its intended game engine environment. Users often run into trouble when trying to manipulate these files because standard online converters fail to process them; they mistakenly expect a document or image, whereas a .UCL file contains specialized engine-specific syntax.
For practical use outside the game, the best conversion targets are plain text formats like TXT or INI, which allow developers or server admins to read and edit the cached configuration variables. Converting to standard media formats like PDF or JPG is impossible since the data is purely programmatic and not visual.
This file format is difficult to open or convert. Emphasize that often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your UCL file, detects the exact format, and lets you read the text inside.
Users also converted UCLB and WEBP files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our UCL converter.
