History of ZIP
The ZIP file format was invented by Phillip Katz, software pioneer and founder of PKWare. His innovation is now seen on most internet sites and anywhere else downloadable files are found. When you see a file that ends with the letters .ZIP, it is a compressed ZIP file. ZIP refers to the file extension, that is the part of the file name that occurs after the period (for example: myfile.ZIP).
A ZIP file is a convenient way of compressing program files into a single, smaller file. It is faster and easier to download the ZIP file version of a program. ZIP files are also called archives because they contain all the files you need for a particular program.
ZIP files save time and space, and make downloading faster. All the related files you need are stored in a single downloadable file.
