"Zipping is the process of packaging a folder that contains multiple files into a single file (called a ""Compressed"" or ""Zipped"" folder). In addition to combining multiple files into one, the resulting zipped folder typically takes up less storage space. Knowing how to zip files is especially useful when you need to send multiple files to someone either (example: through email or an online course). A Zip folder has a "".zip"" file extension and the icon for the zip folder typically looks like a folder with a zipper. For the recipient to view the files, they would first need to unzip (or Extract) the zipped folder to be able to access the individual items inside."
