This article is about the playing card. For alternate uses of the word see Ace (disambiguation). For abbreviations with the same spelling, see ACE. The word "ace" comes from the Old French word 'as' (from Latin 'as') meaning 'a unit', from the name of a small Roman coin. It originally meant the side of a die with only one mark, before it was a term for a playing card. Since this was the lowest roll of the die, it traditionally meant 'bad luck' in Middle English, but as the ace is often the highest playing card, its meaning has changed to mean 'high-quality, excellence'.

In computing, ACE is a proprietary data compression archive file format developed by Marcel Lemke, and later bought by e-merge GmbH. ACE offers superior compression compared to the ZIP file format, at the cost of a lower compression speed. The file extension is .ace. The MIME-Type is application/x-ace-compressed.WinAce, maintained by e-merge GmbH, is used to decompress and manipulate ACE files under Microsoft Windows. When installed, it lets the user choose between paying for a registration or installing WhenU spyware. Older versions of an extract-only program called "UNACE" were free and licensed under an open source license, but they cannot extract ACE archives from version 2.0 and newer. Besides that, there are some freeware or nagware archivers which can read the format using the official "free" UNACE-DLL, though none are free software as defined by FSF.
