Archive Utility (
BOMArchiveHelper until
Mac OS X 10.5) is the default
archive file handler in
OS X. 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 Mac OS X 10.10,
/System/Library/CoreServices/Archive Utility.app in 10.5 and later, 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.
