In computing, ACE is a proprietary data compression archive file format developed by Marcel Lemke, and later bought by e-merge GmbH. The ACE format can possibly be better than the ZIP file format and take less time to compress.Fact|date=October 2008

WinAce

WinAce, maintained by e-merge GmbH, is used to compress and decompress ACE files under Microsoft Windows. When installed, it lets the user choose between paying for a registration or installing WhenU adware. e-merge GmbH also produces a Commandline ACE for DOS; and a freeware command-line decompression tool for Linux (i386) and Mac OS X called "Unace". e-merge GmbH also provides several libraries for developers, including a freeware decompression DLL called "UnACE.DLL". Some third-party archivers can read the format using this DLL. None of the above is free software.

An older version of an Unace 1.2b was free and licensed under the GPL by the author Marcel Lemke, but it cannot extract ACE archives from version 2.0 and newer.

On November 23, 2007, version 2.69 of WinACE was released, including a less intrusive adware application, MeMedia AdVantage, which replaces WhenU. No other major changes are in this release.
