You can zip (compress) a file so that it takes up less space. This makes it easier to email or move the file. You can also zip multiple files into a single compressed folder. This makes it easier to share a group of files. To open a file that has been zipped, you need to unzip (extract) it first.
Some types of files, like JPEG images, are already highly compressed, so there's no need to compress them further.

Select the file or folder, tap or click Share, then tap or click Zip.
A new compressed folder gets created in the same location with the same name as the file. You can rename the compressed folder like you can any other folder. Just select the folder, tap or click Home, then tap or click Rename.

If you add encrypted files to a compressed folder, they won't be encrypted after they're extracted.

Just be careful when you install file compression apps from the Internet because they might change your settings so that files don't open in the apps you want them to.
To compress files or folders from the Command Prompt window, you can use the compact command. For info about using this command, type compact /help at a command prompt.

To extract everything in the compressed folder, tap or click the Compressed Folder Tools tab, then tap or click Extract all.
If you’re trying to extract everything in a compressed folder and can’t see the Extract all command, select the compressed folder, tap or click the Home tab, then tap or click Properties. On the General tab, next to Opens with, make sure it says File Explorer. If it doesn't, tap or click Change and select File Explorer. If you still can’t see the Extract all command, the .zip file association in the registry might be damaged. Search
