About YFS files

The .yfs file is a proprietary mission and scenario file used exclusively by YSFLIGHT, a lightweight, free flight simulator. These files store crucial simulation parameters, including initial aircraft coordinates, weather conditions, weapon loadouts, and artificial intelligence (AI) flight paths.

The major disadvantage of the .yfs format is its rigid, proprietary nature. The data is completely locked to the older YSFLIGHT game engine. It is impossible to directly export or import these flight scenarios into modern software like Microsoft Flight Simulator or X-Plane. Because of these limits, users who want to analyze mission data outside the game are severely restricted.

If you need to extract the data, your best target format is TXT. Because some game files use simple markup, a basic text conversion allows you to read the underlying coordinates and settings. However, converting these coordinates into standard mapping formats like GPX will usually result in data loss or require manual scripting.

This file format is difficult to open or convert because it lacks widespread documentation and is built entirely for a niche simulation engine. Often only the original software can properly read or export the data. Standard online converters fail because they cannot parse the unique schema. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.

Convert.Guru analyzes your YFS file, detects the exact format, and lets you read the text inside.

The YFS Converter Story

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 YFS converter.
