This program identifies the file format of movie files
and displays information about them. It identifies
all popular movie file formats, including AVI, DivX,
ASF, WMV, MPEG-1, MPEG-2, QuickTime, and RealMedia.
It also lists the audio and video formats. The
program is stand-alone and does not require any
installed multimedia libraries or codecs. It's great
for files that are incorrectly named (wrong extension)
or for finding out which codecs you need.
