It's surprising that there are so many file types that seem relatively common which are missing from this list. There are no raw image file formats. There's nothing for CAD - either source files or neutral files. There's no MIDI files, or any other music creation types. There's no APL, Pascal, COBOL, assembly source file formats etc.

Well, what they used this for at Google was apparently scanning their user's files for things they shouldn't store in the cloud. Probably they don't care much about MIDI.

Worse it seems that for unknown formats it confidently claims that it is one of the known formats. Rather than saying "unknown" or "binary data".

No tracker / .mod files either, just use file.

Thanks for the list, we will probably try to extend the list of format supported in future revision.

Yeah this quickly went from 'additional helpful tool in the kit' to 'probably should use something else first'
