VoiceOver System components Archive Utility Archive Utility (BOMArchiveHelper until Mac OS X 10.5) is the default archive file handler in macOS. It is usually invoked automatically when opening a file in one of its supported formats. It can be used to create compressed ZIP archives by choosing "Create archive of 'file'" (Leopard: "Compress") in the Finder's File or contextual menu. It is located at /System/Library/CoreServices/Applications/Archive Utility.app in OS X 10.10 and later, /System/Library/CoreServices/Archive Utility.app in 10.5 through 10.9, and /System/Library/CoreServices/BOMArchiveHelper.app in 10.4 Prior to Archive Utility's inclusion in Mac OS X v10.3, beginning with Mac OS 7.6, Apple bundled the freeware StuffIt Expander with the operating system. Invoking Archive Utility manually shows a minimal GUI letting the user change Archive Utility preferences or choose files to compress or uncompress. BOM is an abbreviation of Bill of Materials.
