The ZIP file format explained
ZIP files are one of the most popular ways to save disk space and send large files and folders to other computers. The process for creating a ZIP file or folder is different depending on what device you’re using. We’ll explain how to zip files for Mac and Windows users. We will also offer methods for file storage and sharing that are more efficient and reliable.
A ZIP file is one or more compressed files together in one location. When a file or folder is zipped, its contents are compressed. With redundant data removed, they need a lot less data to store and share. The process is called “lossless data compression”. Lossless meaning that while the file size is reduced, the file itself isn't affected. ZIP is a type of file archive. There are other formats, like RAR and 7-ZIP, but ZIP is the most common.
Why should I zip files?
ZIP files can be useful if you’ve got a large group of files or even one massive file that you need to share. A lot of email clients won’t allow you to send huge files. So file compression is often seen as one of the best solutions for sending bigger data. You can also use ZIP files to encrypt private data before sending it online.
How to zip a folder or file on Mac
If you’re compressing many files together on a macOS, you’ll need to make sure they’re contained in the same folder. Create a new folder with only the files you wish to compress. You can then right-click or Ctrl-click that folder and select “Compress Items.” The .zip file will save in the same location of the original folder.
You may only want to compress certain files in a folder but not the entire folder. To do this, hold down the Command key and then click on whichever files you want zipped. When they’re all selected, right-click and select 'Compress [#] items.” All items will compress into a single ZIP file, called “archive.zip.” You can change the name by right-clicking the file and selecting Rename. It’s the same process if you only want to compress one file—right-click on it and select “Compress [filename].”

'Send To' is a similar process for Microsoft users. First, make sure all the files you’re compressing are in one folder. Next, right-click that folder, and then scroll to the “Send To” option. In the 'Send To” menu, you should see the “Compressed Folder” option. Click that, and your compressed file will save to your desktop.
Another way to zip files on Windows is to select the files you want compressed and, in the “Share” tab of File Explorer, locate and click the “Zip” button. You can do this on any Windows computer operating Windows 8.1 or higher. With older computers you’ll need to use the right-click and 'Send To' method.
How to unzip a ZIP file
To uncompress a zip file on Mac, double-click on it. You can also right-click on it, hover over “Open With,” and select “Archive Utility.” The file will unzip and a new folder will be created with the files, in the same location of your stored ZIP file.
On Windows, you can view the contents of a ZIP folder without unzipping it. But can’t edit them unless you extract the files. To do so, right-click on the ZIP folder and select “Extract All.” The files are then extracted and stored in the same location as the ZIP file. You can set a different location by pressing “Browse” in the Extract All wizard. You can also do the same for individual files within a zipped folder if you don’t want to extract everything at once. Right-click the file, select 'Cut,” and then paste it wherever you want it saved.
Add files to an existing ZIP folder
You might already have a zipped folder that you need to add more files to. On Windows this isn’t too complicated. Drag the new files or folders on to the ZIP file, like you would if you were adding a file to a regular folder. These files are now added to your ZIP file.

For Mac users, your options are more limited. There’s no way to directly password protect a ZIP file on Mac. You’ve got to do a bit of legwork using Terminal. This is quite a complicated and, considering the other options available, unnecessary process. Again, there are plenty of third-party apps that you can use to protect ZIP files on both Windows and Mac.
