Compressing Email Attachments with the Mac OS X Compress Feature

The Compress Feature

The Mac OS X operating system provides a bult-in feature for compressing files and directories. It's accessed using the shortcut menu associated with a file or folder icon.

Creating a Compressed Archive

Access the shortcut menu for the file or folder that you want to compress by either control-clicking on the icon or, if you have a two-button mouse, right-click on the icon.. There will be a menu entry with the name Compress "<file or folder name>" (in older versions of OS X, the command appeared as Create archive of "<file or folder name>").



Click on this and a file will be created in the same folder (or on the desktop if you're working on the desktop) with the same name as the original file with the extension ".zip". You can use this ZIP file as an attachment in an outgoing email message.

If you have questions about using the Mac OS X Compress feature, please consult the Mac OS X Help system, or contact your computer support resource.
