Hi! Please describe that "normalizing" process which makes
the source codes inside the distro packages behave like a
solid archive. If you remove them from the ZIP and add a
TAR of the sources to the ZIP instead, you would get that
type of result, but it would mean that the install process
will have to be modified significantly. Also, you would
need temp storage for the TAR because DOS has fake pipes.

  2,586,758,742 bytes, original total ZIP size
  2,535,458,056 bytes, after `advzip -k -p -z -3 `

...

But normalizing the source code that is bundled in distro packages is
where the big savings happen because it makes the most compressible part of
the archive behave like a solid 7Z file.

...

The advzip output is indeed compatible with both pkunzip-2.04g and
pkunzip-2.50 running on a DOS machine with one megabyte of memory.

The way AdvanceCOMP checks and retains metadata is satisfying. If you run advzip on the entire FreeDOS collection, then you'll notice a non-trivial
number of malformed and/or corrupt ZIP files.

You mean they were already malformed before you recompressed them?
Can you provide a list of those damaged ZIP files to us?

Thanks! Regards, Eric
