It would be nice if there could be support for Ace in the future. Although is not a
main format and I think the program already support most of the common formats.

From mail:

There are source codes for unace 2.0:
http://packages.debian.org/source/sid/unace-nonfree
This orig.tar.gz+diff works (at least I was able to port it to OSX and Android).
Also I'll be glad if you support unegg:

With the architecture The Unarchiver uses, calling external programs is extremely inconvenient
and not 
necessarily possible at all, so that is not really an option.

WinAce makes a program called "Unace for Mac OS X 2.5"
(http://www.winace.com/down.html). Presumably you could just include it and make an
external command-line call to this program.

paracelsus:

The Unarchiver only supports ACE 1.0. ACE 2.0, which your file probably uses, is
undocumented and there is no open implementation of it to use, and thus it will most
likely not be supported anytime soon.

gireal:

It turns out the file was encrypted, but The Unarchiver did not prompt for password
or mention that it was an encrypted file.

After seeing the known issue with encrypted files this issue can probably be ignored
-- but it would be nice to have the error message mention that it failed due to
encryption.
