Free ACE software, open, extract ACE
PeaZip offers read-only
(open and extract / unizp ace files) for WinAce's ACE
archive format, providing a free
WinAce alternative utility to original closed source application for
(list/browse content) and extracting .ace archives (unace) under Windows
and Linux operating systems - including password protected ace archives.
The software can also convert ACE files to any other write-supported
format (i.e. re-pack and convert existing ace file into zip, 7z, etc).
Due to the closed source nature of the unace
tool, it is provided as separate
add-on for PeaZip (other PeaZip project packages only feature Open
Source software released under OSI approved licenses), please refer to UNACE Plugin page for instructions
about downloading and installing the add-on.
free unace utility supports extraction of ACE archives trough
by WinAce author as royalty free (but closed source) component - note
for Linux users: UNACE is a 32 bit x86 executable, so on Linux 64 bit
systems it requires ia32-libs to extract ACE files.
Windows platform UNACE plugin is based on abandoned closed source
unacev2.dll, the last made officially available from WinAce team, which
is known to be not longer safe to use due unpatched vulnerabilities.
Out of the box, PeaZip does not come with
unacev2.dll (which requires separate manual download and installation
from user) so it is immune to said vulnerabilities. No version of
PeaZip will attempt to automatically download or install UNACE plugin,
nor will use UNACE plugin (even if installed) to open ace files
disguised for other formats.
plugin for Windows is offered as legacy component with the sole purpose
of supporting trusted ace archives (with the recommendation of converting existing ace files to a
better supported format); untrusted ace archives should not be opened
using tools based on unacev2.dll.
Help > About screen reports if UNACE plugin is installed and
features a button for quick removal of the plugin.
Create / update ACE files
for ACE files is read-only, the application cannot write
to .ace file format to create
a new archive or update
an existing archive.
No royalty free Open
Source archiving tool is known to implement creation or
modification / update of existing ace files.
As ACE format is
proprietary, and not update in recent years, it is a
good practice to convert legacy .ace archives in a mode modern, widely
supported, and actively maintained format, possibly not encumbered by
patents, like 7Z and ZIP.
To convert ACE files
write-supported archive format is possible using the
integrated file conversion procedure, which extracts and then re-pack
input archive files,
or deleting original
