If you frequently send or download things, your share of "zipped" files has probably occurred. These files have been compressed to reduce the file size so they can be uploaded or downloaded faster. If you're a Mac user, you may want to know how to use these files to transfer data, whether for business or personal use. To create a ZIP file on a Mac.
What is a ZIP file?
If you have a lot of data to send, you may be wondering how long this will take. This can be particularly problematic for music or video files. Depending on the format, uploading or downloading may take hours. The way to do this is to compress the files by either eliminating redundancies in the files that can then be recreated (lossless compression), or by cutting out unnecessary bits, even though this costs a perfect replica (lossy). Compressed files are packed in various archive formats such as RAR and ZIP. When you download a compressed file, you must extract or "unzip" the content to access it.
Creating a ZIP File on a Mac
Creating a ZIP file on a Mac is quick and easy because MacOS includes an integrated utility for compressing or unzipping files.
First, find a file or group of files that you want to compress. For a single file, just right-click on it and select Compress [file name].
You will see a ZIP file in the same folder as the original that still exists.
To compress multiple files into a ZIP file, select them all, right-click and select Compress X Elements where X is the number of highlighted files.
A single archive file is displayed in the folder where the originals are located.
How to Unzip a File
Unpacking a ZIP file is as easy as creating one. Just double-click on the file and it will automatically unpack. Alternatively, you can right-click on the file in question, hover over Open with and select Archive utility (or a third-party unpacker, if any).
MacOS automatically creates a new folder with the compressed files in the same location as the ZIP file. If you want to secure your ZIP files with a password, we also have instructions for this.
