 Zipped FilesFiles archived in a Zip file are compressed to save space. We use this format throughout our website for very large files so they may be downloaded more quickly. Many files on the Net are in a compressed format. Typically, these files will have a .zip extension. Zipped files must be unzipped (or decompressed) before viewing. Besides the popular ZIP format, there are many other compression formats, such as Stuffit (.sit) files (for Mac users) and uuencoded (.uue), BinHex (.hqx), ARC (.arc), Arj (.arj), and gzip (.gz) formats, etc. One of the most popular and well-known compression utilities is WinZip. The link we are providing is to get the trial version. You are expected to pay for it if you use it and like it. To get WinZip, click on: Get Winzip . The following site has several freeware zip programs that are very good programs. To see the free software, click on: Free Zip Software. |
