Try a file command on some specific file and see what it says, then
change the extension and do the same again. The identified file type is
not determined only by the extension as you would find out, and as Leon
said above.
In *nix systems file types are NOT identified only by the extension as
they are in the windows world and this warning is telling you the file
type is not properly designated by the extension.

Wmv video and asf video are two entirely different animals handled by
different codecs and can have different risks associated.
