What is an FPL file?
An .FPL file is a data file that can belong to several different software applications. The most common format is the Foobar2000 Playlist File, which stores a list of audio tracks and metadata for the foobar2000 music player. However, an .FPL file can also be an Aviation Flight Plan used by Garmin navigation devices, a Floor Plan User Library for the Floor Plan Creator app, or a Future Pinball Table for the Future Pinball game simulator.
How to open FPL files?
Because the .FPL extension is shared by many completely different programs, you must identify the correct format first. You can open a Foobar2000 Playlist File directly in the foobar2000 audio player. For aviation flight plans, you can import the XML data into Garmin Pilot or ForeFlight. Floor plan libraries require the Android-based Floor Plan Creator app to view the zlib compressed contents.
Inspecting unknown FPL files
If you do not know which application created your file, viewer.online/fpl can analyze .FPL files to identify the exact format and creator software. It allows you to inspect the file structure, extract readable text, and check whether an online preview is available. For example, Garmin flight plans use readable XML text, while playlists and floor plans use custom binary code that our tool can parse and inspect.
Best practices and troubleshooting
Do not change the file extension to guess the format. Renaming the extension will not change the underlying data and can corrupt the file. If a file fails to open in your audio player, it is likely a flight plan or a database file instead.
Summary
viewer.online/fpl is useful for identifying, inspecting, and understanding .FPL files without installing software or dealing with compatibility problems. Since .FPL has multiple possible meanings, we recommend using viewer.online/fpl to identify the actual format of your file quickly and safely.
