What is an FDA file?

FDA files mostly belong to Varies by origin.

FDA file variations: FDA files are not a single format. Their use depends on the source and context in which they were created. They include:

• Relic Entertainment Audio Files: These store game audio data using a proprietary Relic Chunky File Format.
• Topcon OCT Files: These hold Optical Coherence Tomography data from medical imaging devices. For more details, see the Topcon Healthcare page.
• MATLAB Filter Design Data Files: Used within MATLAB to save filter design parameters and related simulation data. Visit MathWorks for more info.
• HERE Map Data Files: These contain navigation data used by HERE Maps Navigator; they assist devices like those from Garmin. More information is available at HERE Navigation.
• Multisim Bitmap Image Files: A less common use, these store bitmap images for specific engineering applications, viewed with FDAView. Further details can be found at FDAView.

Usage and Opening:
If you encounter an FDA file, determine its origin. The right application—whether a game audio tool, medical imaging software, MATLAB, navigation program, or image viewer—is needed to open and view its contents. Check for file headers or metadata for clues.

Functionality:
FilExt.com notes: Each variant is optimized for its field. They differ internally: one may compress sound, another store scan data, while others hold design parameters or map details. This showcases the versatility hidden behind one extension.

How to open an FDA file

FDA file extension format:

To view or edit FDA files you need to know the file format, because it determines how the data in this file is stored. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. If there are problems opening a file, you must first determine the file format used. Our evaluation of the FDA files looks like this:

The FDA file type includes various formats for various programs. However, the following two file formats are common:

• 30% of all FDA files use the same file format, which can be identified by the letters "FO" at the beginning. They consist of unreadable binary data. The files are 1 MB to 40 MB in size, with a median of 11 MB. The file type was developed only in the last few years. The keywords @HW_INFO_03, FOCTFDA, @FDA_FILE_INFO( and DOCT are typical for these files. The file name eg_oct_fda.fda is typical for these files.
• 30% of all FDA files use the same file format, which can be identified by the letters "Relic Chunky " at the beginning. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are often between 33 KB and 10 MB in size. The following keywords are characteristic: DATAINFO, Relic Chunky, DATAFBIF, FileBurnInfo, RAW to FDA, DATADATA and PMFOLDFDA. These files can be linked to music, selection, theme, uamod, character, angels, death, loop and menu.

All the rest of the FDA files (40%) have different formats, the following 5 formats exist: MATLAB and RIFF. These files are often connected to here, filter, qualification or nanalysis. Just click the "Choose your .fda file to analyze" button on this page to find out what your FDA file is.
