If you order custom or purchase my products from the marketplace, you will find that they are zipped files. I do this so it makes for easy delivery and unpacking. It compresses multiple files and folders to one zipped file, so you can save space and storage. In order to open these files, you must have an unzipping program on your computer. Windows 10 has a built in system to unzip files. WinZip or 7zip are programs that will extract zipped files.
