About FTL files
A .FTL file primarily functions as an Apache FreeMarker Template Language file. Developers use these files in Java applications to generate dynamic web pages, emails, or XML files. The FreeMarker engine combines the template text with Java objects to produce the final output. Alternatively, gamers encounter .FTL files as modification packages for the game Faster Than Light. In reality, these are just standard ZIP archives renamed to bypass default extraction tools, typically managed by utilities like Slipstream Mod Manager. Other less common uses include 2D structural analysis models in Ftool, legacy family tree data in Family Tree Legends, and localization text files in Mozilla's Fluent Translation List system.
Working with .FTL files often presents practical challenges. FreeMarker templates contain raw code, macros, and variables that are useless to non-developers without a backend rendering engine. They cannot be opened directly in a web browser. FTL game mods confuse users because they appear as proprietary files instead of standard archives, preventing immediate access to the audio and image assets inside. Legacy Family Tree Legends files require outdated software that is largely abandoned and incompatible with modern systems.
Converting your .FTL file solves these accessibility issues. If you have a FreeMarker template, convert it to TXT or HTML to edit the raw markup in standard text editors. If you have an FTL game mod, convert or rename it to ZIP to effortlessly extract the assets inside. For legacy data, convert to universally supported formats.
Convert.Guru analyzes your FTL file, detects the exact format, and lets you read the text inside.

The FTL 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 FTL converter.
