Zipping a file creates a compressed version of the file that is considerably smaller than the original file. The zipped version of the file has a .zip file extension. For example, if you zip a Microsoft Office Word document called workshop.doc that is 6.5 megabytes (MB) in size, the file created, workshop.zip, is reduced to 2.5 MB. To use the original file, workshop.doc, you must first unzip workshop.zip.
