Since macOS is based on Unix there are a number of ways to compress files and folders within the filing system using Unix based application code, below are a few options using the Terminal or command line interface (cli). The default command line application interface in macOS is the Terminal and is stored in /Applications/Utilities.
Apple Mac OS X Lion is now available to general public. The Mac OS X 10.7 Lion is available for installation only from the Mac App Store. This guide will teach you how to create a bootable USB Flash drive of Mac OS X Lion 10.7 and install Lion from USB, rather than downloading it from Mac App Store on each and every Mac computer you own. Mac OS X Lion (version 10.7) is the eighth major release of Mac OS X (now named macOS), Apple's desktop and server operating system for Macintosh computers. A preview of Mac OS X 10.7 Lion was publicly shown at the 'Back to the Mac' Apple Special Event on October 20, 2010. It brought many developments made in Apple's iOS, such as an easily navigable display of installed applications, to the.
File and folder compression saves on file size and ensures the contents are captured and delivered or stored as one monolithic file. A compressed file which contains files and folders is generally referred to as an archive. Here are some built-in compression applications you can use including zip, tar, gz, bz2, gz and dmg.
ZIP – Cross Platform
First up is ZIP one of the most commonly used compression techniques used across all platforms
If you want to make a zip without those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files, use the “-X” option in the command so:
TAR.GZ – Cross Platform
Second up is TAR, an old favorite on Unix/Linux – you add the GZ for the compression – compresses tighter than zip
TAR.BZ2 – Cross Platform
A variation on TAR GZ but with better compression than both tar.gz and zip.
Without the tar
Mac Os X Terminal
DMG – macOS Only
This one is macOSnative only – for a GUI interface use /Applications/Utilities/Disk Utility – for command line use:
You can also use a number of different formats for creating a .dmg Shift f3 for mac.

- UDZO – Compressed image (default)
- UDRO – Read-only image
- UDBZ – Better compressed image
- UDRW – Read/Write image
- UDTO – DVD disk image
That’s the low down, the more common compression packages available will typically be covered in one of the above.
