The FGEN Soft Front Panel (SFP) application allows users to select an input file containing waveform data for demonstration. Files of various formats are listed in a popup prompt window. How does SFP identify the type of the data in the files? Does the file extension (.bin, .lvm) indicate what's inside?

If you installed NI-FGEN in the default directory, then C:\Users\Public\Documents\National Instruments\NI-FGEN\examples\Waveforms\Waveformdescription.txt should have descriptions of each of the example waveforms and what is inside the file.
The NI Signal Generators Help file (Start > All Programs > National Instruments > NI-FGEN > Documentation) has the Waveform File Specifications under Interactive Tools > FGEN Soft Front Panel > Waveform File Specifications.
The SFP does use the file extension to determine the file type. As a simple test, I renamed the fgMode-square.bin example file to fgMode-square.lvm. When I tried to load the renamed file, it gave me an error declaring that the file is not a valid LabVIEW Measurement File (lvm), thus proving the software checks the file extension to determine the contents.
