Hmmm...that's intersting.  So I take it AosHTTPServer
assumes the "last" "." is the one not to convert?
What I mean is:




Rather than


Anyway, that still doesn't cover what I was talking
about with regards to user permissions.  Unless
there's someway in AosHTTPServer to assign
certain permissions to any file prefixed
with my.folder.structure.

In theory yes.  In practice?  Not typically.  
I think one of the reasons computers often have
such deeply nested file structures is....because
you can have such deeply nested file structures.
There have been many times I've "drilled down" 
many levels deep only to find a single file, 
or worse an empty folder.

Remember the example I gave of Leonardo.Text?
Someone could structure that as:

/Program Files/Leonardo/Documentation/Readme.Text

but is that REALLY necessary?

Finding something in:


isn't exactly simple either.

Only if you make the user interface look like 
folders.  I often use "Prefix.*.Suffix" from
the Documents.Panel.  It looks nothing like
folders (to me anyway).  I find (pardon the
pun) this a faster way to find stuff than
"drilling down" in folders.  I like the fact
that Plugin Oberon shows all the files in
the "Directories" list as together in one

Again, from my own experience, many "file folders"
could go away with a little forethought.

And what would that really show?  There's a
lot on my Windows box that's not part of MY
directory structure.  (i.e. everything under
C:\Program Files)  I typicially don't have
folders more than 4 deep for things I set
up myself.
