A ZIP file is a compressed archive of a set of files. Archives are files that contain other files. Typically the files in an archive are compressed. Archives usually have file names ending with CAB, ZIP, LZH, ARJ, or ARC, depending on how they were created. Archives make it easy to group files and make transporting and copying these files faster. Compressed archives also reduce the space required to store a set of files on a hard disk or floppy disk. ZIP is the default extension of zipped files. WinZIP by Nico Mak is a popular utility with GUI interface to manipulate ZIP files. A typical window for WinZIP is shown in the next figure.
