Learn how to zip and unzip files on your Mac, including how to create password-protected ZIP files. It is easy to compress a single file or multiple files and folders into a ZIP file archive on your Mac. You can also decompress any ZIP file by simply double-clicking it. The Archive Utility is used invisibly for both commands, and there are some settings you can access. If you want to create password-protected ZIP files, you can do it with the Terminal.
Are these types of password protected ZIP files compatible with Windows or only Macs?
Douglas: ZIP files are not platform-specific.
Thank you, Gary. The reason I asked is because there have been times that I created password-protected ZIP files on either Mac or Windows and I ran into a problem on the other platform trying to extracting the contents.
