In computing, ACE is a proprietary data compression archive file format developed by Marcel Lemke, and then purchased by e-merge GmbH. The peak of its popularity was 1999-2001, when it gave a slightly better compression level than RAR, which has since become more popular.

WinAce
WinAce, managed by e-merge GmbH, is used to compress and decompress ACE files under Microsoft Windows. When installed, it lets users choose between paying for registration or installing WhenU adware. e-merge GmbH also generates ACE Commandline for DOS; and a freeware command line decompression tool for Linux (i386) and Mac OS X called "Unace". e-merge GmbH also provides some libraries for developers, including a freeware DLL decompression called "UnACE.DLL". Some third-party archivists can read the format using this DLL. None of the above is open source free software.
The old version of Unace 1.2b is free software and licensed under the GPL by author Marcel Lemke, but can not extract the ACE archives from version 2.0 and later. The latest version of Unace 2.5 that supports the ACE 2.0 archive is available under a strict open source license, as well as by Marcel Lemke.
On November 23, 2007, version 2.69 of WinACE was released, including a less intrusive adware application, MeMedia AdVantage, which replaces WhenU. There are no other major changes in this release.

Third party support
Packaging ACE files are licensed as proprietary information and only available through WinACE, while dismantling ACE files supported by a number of third-party archiving. However, almost everything (which supports ACE 2.x format) does this by using "Unace.dll" from e-merge GmbH. Since 2017, there is a BSD licensed python module that supports dismantling the archive of the ACE 2.x format.
