Thanks, Andy - yes, it told me what the files were, and its best guess was good. (I should know - I created the files!)
But no actual magic numbers. :-(

In Windows world, you have file extensions, no magic....

In Mac world, the file/directory entry has, I believe, application identifiers.

In Linux world, it is not worked out by extensions or extra attributes on file/directory inodes, but rather on the content of the file. The "magic" numbers might be similar in way of use as to the IANA ports or services -- that is, the magic numbers are arbitrary. Content is king to evaluate the so called "magic".
