Zipped (compressed) files take up less storage space and can be transferred to other computers more quickly than uncompressed files. In Windows, you work with zipped files and folders in the same way that you work with uncompressed files and folders. Combine several files into a single zipped folder to more easily share a group of files.
By default, the extracted ZIP folder—which is just a regular folder with the same name as the ZIP folder—will open as soon as the extraction is complete. If it doesn't, double-click the extracted folder to open it like usual. Once you've extracted the ZIP folder, you can use the files inside of the extracted folder like you usually would.

How To Zip Folder Mac
To add files or folders to a zipped folder you created earlier, drag them to the zipped folder.
If you add encrypted files to a zipped folder, they'll be unencrypted when they're unzipped, which might result in unintentional disclosure of personal or sensitive information. For that reason, we recommend that you avoid zipping encrypted files.
Some types of files, like JPEG images, are already highly compressed. If you zip several JPEG pictures into a folder, the total size of the folder will be about the same as the original collection of pictures.
