I have received a file with .zip extension but I don't know what to do with it. What should I do?

The .zip extension of a file indicates that it has been compressed with the Winzip program. Compressing files reduces the size of the files. Therefore, compressor programs such as Winzip are highly useful for sending files by email or simply as a file storage system, as they take up less space on the hard disk.
