To zip (compress) files, you must have a ZIP file program on your computer.

Windows XP Professional now comes with a built-in compression utility, and to compress files under this operating system, right-click a file, select Send To, and then click Compressed (zipped) Folder. A new zipped folder containing the orginal file is now created. To change the name of this folder, right-click the folder, select Properties, and then enter a new name. Additional files can be added to the folder by using the drag and drop method.

For other operating systems, the installation of a third-party ZIP file program is necessary to successfully compress files.

Although there are several programs that manage files of this type, the tutorials below cover the 2 most popular utilities in this category, PKzip and WinZip.
