Extract text from Flex library files (FXPL)
To convert FXPL libraries to another format, you need Adobe Flash Catalyst or other Developer software.
To convert other file formats to the "Flex Project Library" file type, you need software like Adobe Flash Catalyst or a similar tool.
The .FXPL file format is an Adobe Flex Project Library package created by the now-discontinued Adobe Flash Catalyst and Adobe Flash Builder. It was primarily used by development teams to distribute reusable interface components, custom skins, and project assets for Rich Internet Applications (RIAs). Under the hood, the file is a compressed package containing MXML layout files, AS (ActionScript 3.0) logic, and raw media assets like images or video.
Because the Adobe Flash platform was officially retired in 2020, and Flash Catalyst itself was killed off in 2012, the .FXPL format is essentially an obsolete artifact of a dead ecosystem. It is proprietary to Adobe's legacy tools, meaning modern code editors and web browsers cannot natively open or interpret the interactive UI elements inside. Trying to access these files today without a 15-year-old software installation is a major frustration for developers trying to salvage old code.
If you need to recover the contents, the best conversion target is a standard ZIP archive. By extracting the file, you can access the underlying XML, PNG, or JPG assets. Converting the interactive Flash components directly to modern formats like React or HTML5 automatically is impossible because the ActionScript logic does not translate cleanly.
This file format is difficult to open because it relies on Adobe's discontinued Flex framework.
Convert.Guru analyzes your FXPL file, detects the exact format, and lets you read the text inside.
If you want to convert FXPL file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Adobe Flash Catalyst or similar software from the "Project Asset Distribution" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to FXPL, try Adobe Flash Catalyst or another comparable tool in the "Project Asset Distribution" category.
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 FXPL converter.
