Zipped files are files that have been compressed to reduce the file size, thus making them easier to upload and download and also making way for a little space.
Mac owners might wish to know how to use these files to transmit data for various reasons. When there is a need to transmit large amounts of data, it could mean long hours spent doing that, which may not be convenient, therefore the need to make it a ZIP file arises.
When you compress these files, it becomes way easier and faster to transmit them. To do this, there are two ways: either the system cuts out redundancies in the files, which can be recreated later (lossless compression), or the system cuts out unnecessary parts completely.
This is known as lossy compression, and it means that your files will not be the same as before. Compressed files are packed in to various archive formats, including ZIP and RAR. When you download a compressed file, you will need to extract the contents, or unzip them.
MacOS has a built-in utility for compressing and unzipping files. Thus, creating a ZIP file on a Mac is quite simple.
To do that, first look for the file or group of files you want to compress. For a single file, simply right-click it and select Compress. Automatically, a ZIP file will be created in the same folder as the original, which will still be present.
To compress multiple files into a ZIP file, select them all, then right-click and select Compress X items, with X being the number of highlighted items. A single Archive file will appear in the same folder as the original files.
That’s that for creating a ZIP file. Now, to unzip a zipped file is just as easy as creating one. All you need to do is right-click the ZIP file you want to unzip, then hover over Open With. Next, select Achieve Utility, or a third-party unzipping program if you have one. Automatically, MacOS creates a new folder containing the zipped files in the same location as the original file.
