Thanks for the correction. My bad <g>. But doesn't this mean that the 
data _is_ in the individual files?

And of course I may again bear correction, but I'm confused - why 
can't metadata (data about the data) be part of the data? I used to 
write file headers and such that contained information about the rest 
of the content and never realised that it wasn't metadata.

This search also made me wiser as I discovered that "Metadata" is an 
Incontestable
registered U.S. Trademark. Go figure. So I'll begin to use meta-data...

'tis as said. [Reality is defined by being described]
