Compress a file or folder: Control-click it or tap it using two fingers, then choose Compress from the shortcut menu. If you compress a single item, the compressed file has the name of the original item with the . zip extension. If you compress multiple items at once, the compressed file is called Archive.
How to compress a file on your Mac
Just make sure to keep the can of compressed air completely upright or you risk damaging the laptop by having the accelerant spray out in an extremely cold spray. The cold and liquid can damage equipment. Follow the instructions in the Apple article @BobTheFishserman provided.

Compressed gas and compressed air are important sources of energy that can be used as fuel. The key difference between compressed gas and compressed air is that compressed gas contains natural gas, whereas compressed air contains a mixture of gases having a composition similar to atmospheric air.
We all know the importance of drying compressed air. It's a crucial step in the compressed air process that, if skipped, can lead to gallons of water building up in your system. But why is compressed air wet? The simple answer is that air always contains moisture.
While air embolisms are usually associated with incorrect diving procedures, they are possible with compressed air due to high pressures. While this seems improbable, the consequences of even a small quantity of air or other gas in the blood can quickly be fatal.
This phenomenon occurs due to the expansion of the compressed refrigerant liquid as it dispenses through the aerosol valve and flashes to a gas. If the aerosol is operated for a long period, frost may form on the can because it is freezing the surrounding water vapor from the air.
Compressed air is clean, safe, simple, and efficient, as far as energy sources go. There are no dangerous exhaust fumes or other harmful by-products when compressed air is used, and it is a non-combustible, non-polluting utility.

File Size. An increase in file size is another disadvantage of compressing files. In some situations including compressing video and audio files, the file you are compressing cannot be made smaller, resulting in a compressed file that is larger in size than the original file.
File compression reduces the amount of space needed to store data. Using compressed files can free up valuable space on a hard drive, or a web server. Some files, like word files, can be compressed to 90 percent of their original size.
1 Answer. From this blog post, it seems dpkg-deb handles compression. And from man dpkg-deb for 14.04: -Zcompress-type Specify which compression type to use when building a package.
Not only does file compression enable you to move files around on a local device more efficiently, it also enables you to send large documents and data faster over the internet. Uncompressed files can often become corrupt when sent over the web.
Low Computer Memory. This may cause your computer to pause. What's worse, you may run into some errors (Low Resources or Out of Memory) if your computer does not have enough memory. To avoid these errors, you should close the applications running in the background and then open the compressed files.
