The new version of AutoDoubler (v2.0) comes with an additional program
called
"AutoDoubler Internal Compressor" which does precisely this.  It is a
resource
compressor that will open much faster than normally compressed files,
will work
on files in the system folder (including extensions and control panels),
will
work on Macs without AD on them, will maintain their compressed size when 
copied to an external disk, and compresses nearly as small as with
standard 
compression (in some cases, even smaller).  However, this compression is
not
done on the fly the way most AD compression is done.  You do it once and
forget
about it.

See above.

This does not happen with AIC (see above), and in normal AD compression,
it 
is only an option, anyway.

Under Sys7, CopyDoubler allow for this.  AIC (see above) is a "permanent"
compression, so decompression in unnecessary.  (Permanent only in that you
must physically request that the file be decompressed.  AIC compression
and
decompression is not done automatically.

AIC will compress files with resources---applications and extensions.  AD
is 
needed to compress datafiles.

I have been very pleased with AutoDoubler/DiskDoubler.  My only complaint
is
that it does not handle other types of compression/decompression or 
coding/decoding so that I still need to keep other compression utilities
available.
