If the files are very large even in the archive, then they can be stored in volumes. Mac compressed files can be either packed or unpacked. This conversion of the file allows you to make the archive on the user's computer much larger without any additional costs for a peripheral storage device for information data. The most important thing if you reduce file size on Mac is that the copy of the document it contains is of the same excellent quality as it was before the compression process. This means that the transfer rate (the time to download file) is higher. In addition, such files are more protected from both hacking and computer viruses.Compressed files contain fewer 'bits' of data than uncompressed files and, as a result, use less bandwidth when downloading them. The time for copying archived files is way less. That is why by compressing files Mac users can store more files on their computers with no need to buy any additional devices.
Storage space, such as a computer's hard drives, cost a fortune. The Smaller size of files the easier to store as well as transfer files from device to device. For example, to save free space in the device storage. Why do people use file compression оn Mac or any other computer? Well, archiving is used in several cases.
