ZIP files are special files that shrink (compress) files so that they will transfer faster from the Internet to your computer.  A single ZIP file can contain many individual files that will be expanded after the data is decompressed. The ZIP format is used by many file compression programs. In order to use a file that has been compressed into a ZIP file, you must have a compression/decompression software program.   There are many free "zip programs" available, and once installed they will automatically decompress a file with the .zip extension.  You can immediately download a free trial copy of WinZip^®  by Clicking Here.   

Note: You can trust the files you download from the Grover website, but zip files can be used to transmit viruses. Whenever you download a zip file, make sure you have an active and current anti-virus program running that scans for viruses in the compressed files.
