If you have lots of large files or folders on your Mac, it is wise to compress them in order to get more free space, for compressed files take up less space on your Mac's hard disk than uncompressed files. In general, compressing files in modern operating systems is a complex technique to learn. But don't worry! Here I'll show you how to use Mac's built-in file compression tool and a highly recommended Mac file compressor to compress files or folders on Mac.
Before you start to compress files and folders, there are two things you have to know. Firstly, you have to understand that not all files can be compressed by a significant amount and you may not be able to compress a file much smaller than its original size. Generally speaking, a zip file will be about 10% smaller than all of the files were before compressing. This feature works best with medium size files - compressing lots of small files or one or two big files won't save you much space. Secondly, the Mac's built-in compression and decompression option uses the ZIP format, and if the files are large, you won't be able to use your Mac operating system's built-in compression tool to compress them. So you'd better use a professional third-party Mac file compressor - Cisdem Unarchiver to help you compress large files and folders. Below we will show you the detailed operating steps of the two ways to compress files and folders on your Mac.
