Zip and unzip files and folders on Mac
Compressed files take up less disk space than uncompressed files, so compressing is useful for making backup copies of your data or for sending information over the Internet.
On your Mac, in a Finder window or on the desktop, do any of the following:
Compress a file or folder: Control-click it, then choose Compress from the shortcut menu.
If you compress a single item, the compressed file has the name of the original item with the .zip extension. If you compress multiple items at once, the compressed file is called Archive.zip.
Unzip (expand) a compressed item: Double-click the .zip file.
The unzipped item appears in the same folder as the .zip file. If you want to, you can delete the .zip file.
Note: If you can’t open the .zip file, make sure you have enough space on your Mac for the unzipped item. If you received the .zip file from someone else, there might be a problem with the file. Ask them to zip the file again and resend it.
