Zip files can be used to store large files in one location without taking up much space on your device. They also make it easy to transfer large amounts data from one piece to another. As long as you are able to extract individual files from the zip file, that is.
You can open a zip file from the Mail app or the third-party Gmail App. Press on the file to get your own menu. To save the file to the Files app press the Share toggle at the top right. Then, click Save to Files in a new menu that opens. You can then follow the instructions in the section. www.office.com/setup
