FMS to TXT Conversion Explained
Converting .FMS (Data) files to .TXT (Plain Text) files changes a structured, application-specific data file into a universal, unformatted text document. .FMS files are used by several different applications, most notably X-Plane for Flight Management System flight plans, FARSITE for moisture data, and Trophy Imaging for dental records. Because many .FMS files are already written in plain text or XML under the hood, converting them to .TXT makes the raw data readable on any device without needing the original software. However, this conversion strips the file of its native file association. You gain universal accessibility but lose the ability to plug the file directly back into the simulator or medical software without changing the extension back.
Typical Tasks and Users
- Flight Simulator Enthusiasts: X-Plane users who want to print, share, or manually edit flight plans (waypoints, coordinates, and altitudes) in a standard text editor.
- Data Analysts and Researchers: Professionals extracting tabular moisture data from FARSITE or parsing XML tags from Trophy Imaging databases.
- Chiptune Musicians: FamiStudio users exporting project metadata or tracker data into a readable text format for documentation.
- IT Support: Technicians recovering data from legacy systems who need to inspect the raw contents of an unknown .FMS file to determine its origin.
Software & Tool Support
Because many .FMS files are text-based, you can often open or convert them using standard text and code editors.
- Text Editors: Notepad++, Visual Studio Code, and Apple TextEdit can open text-based .FMS files directly. Saving them as .TXT is a native function.
- Flight Simulators: X-Plane and third-party flight planners like Little Navmap can read .FMS files and export waypoint data.
- Audio Software: FamiStudio includes built-in export options to convert .FMS tracker data to .TXT.
- Command-Line Tools: Linux and macOS utilities like
cat, awk, or sed can parse and convert XML-based or tabular .FMS files into clean .TXT outputs.
Pros and Cons of the Conversion
Pros:
- Universal Compatibility: .TXT files open on every operating system, mobile device, and web browser without specialized software.
- Transparency: Converting to plain text reveals the underlying data structure (like XML tags or comma-separated values), making it easy to audit.
- Editability: Users can quickly find and replace specific coordinates, variables, or text strings.
Cons:
- Loss of File Association: Double-clicking a .TXT file will open a text editor, not the native application (like X-Plane or FARSITE).
- Potential Data Corruption: If the original .FMS file is a binary format (like FantaMorph skins or FamiStudio modules), converting it to .TXT will result in unreadable gibberish and permanent data loss.
- Formatting Loss: Any software-specific rendering instructions are ignored in a plain text environment.
Conversion Difficulties & Why Convert.Guru
The main technical difficulty in converting .FMS to .TXT is handling the multiple variations of the .FMS format. A flight plan uses a specific tabular layout (e.g., starting with I 1100 Version), a dental record uses XML, and a FamiStudio project uses a proprietary binary structure. Forcing a binary .FMS file into a .TXT file causes encoding errors, resulting in a file filled with null characters and broken text.
Convert.Guru handles this conversion accurately by analyzing the file signature before processing. If the .FMS file contains structured text or XML, Convert.Guru safely extracts and normalizes the character encoding (usually UTF-8) to ensure the resulting .TXT file is perfectly readable. It eliminates the guesswork of dealing with unknown file origins, providing a clean, simple, and technically sound conversion pipeline without risking data corruption.
FMS vs. TXT: What is the better choice?
| Feature | .FMS | .TXT |
| Primary Use Case | Application-specific data (Flight plans, XML, trackers) | Universal plain text storage and reading |
| Software Requirement | X-Plane, FARSITE, FamiStudio, etc. | Any basic text editor (Notepad, TextEdit) |
| Data Structure | Strict (Tabular, XML, or Binary) | Unformatted, raw text |
Which format should you choose?
Choose .FMS if you are actively using the file in its native environment. If you need to load a flight plan into X-Plane, run a fire simulation in FARSITE, or edit an 8-bit track in FamiStudio, the file must remain in the .FMS format.
Choose .TXT if you need to share the raw data with someone who does not have the native software, or if you are archiving the human-readable contents (like waypoints or XML records) for long-term storage. Avoid converting binary .FMS files to .TXT, as this will destroy the file's usability.
Conclusion
Converting .FMS to .TXT makes perfect sense when you need to extract, read, or share structured data—like flight simulator waypoints or XML records—outside of their native applications. The biggest limitation to watch for is the format's fragmented nature; while text-based .FMS files convert flawlessly, binary variants will not yield readable text. Convert.Guru is a reliable choice for this exact conversion because it safely handles character encoding and extracts the readable data without corrupting the file, ensuring your transition from specialized data to plain text is seamless.
