how to identify unknown file


Recommended Posts

i have a specific file (size is over 100 MB)

but i can't figure out from header what it is since it was dumped as just file w/o extension

the first line among alot of gibberish produce this:

XFIRÂ'N	LPPApami      }!" @              pamm¨          ˙˙˙˙˙˙˙˙˙˙˙˙XFIRÂ'N


and few liines below it gives these references:

C:\Program Files\Macromedia\Director 8\xtras\Net Support\INetURL.x32D
C:\Program Files\Macromedia\Director 8\xtras\Net Support\NetFile.x32E
C:\Program Files\Macromedia\Director 8\xtras\Net Support\NetLingo.x32
C:\Program Files\Macromedia\Director 8\xtras\Media Support\SWADCmpr.x32
C:\Program Files\Macromedia\Director 8\xtras\Devices\MacroMix.x32
C:\Program Files\Macromedia\Director 8\xtras\Devices\DirectSound.x32
C:\Program Files\Macromedia\Director 8\xtras\Media Support\Sound Control.x32
C:\Program Files\Macromedia\Director 8\xtras\Media Support\Text Asset.x32
C:\Program Files\Macromedia\Director 8\xtras\Media Support\TextXtra.x32


i did try to rename file and add extension of .x32 and .dir
then i tried to open these files in Macromedia Director 8.5 , but it doesnt accept it/them

and if it's .RIFF file, i dont know how to even open it, because for a fact i know it contains VIDEO file
and "internet" only reffers RIFF to be corel image


any ideas ? :P

It is a little-endian RIFF (RIFX) file from Macromedia Director.


Director Movie Files use a RIFX container. The file consists of Chunks, each beginning with a ChunkID (taking the form of a FourCC.) It’s similar to a RIFF container, like what WAV uses, except that RIFX containers can either be little or big endian. If the file is big-endian, it will begin with the ID RIFX. If it’s little-endian, it will begin with the ID XFIR. Whether the file is little or big endian depends on the processor of the computer that saved the file, but Director is always capable of opening files of either endianness.

Quickbms is a tool that needs a sort of plugin/script for each file type.

It simply makes no sense whatever to say "quickbms spews out errors and nothing extracted or given".

There is a RIff parser on its page, that may (or may not) work "as is".

Very likely what you have in your hands is a corrupted file (hence the Macromedia cannot open it) and it is possible that the Riff plugin may need some tweaks/changes.
