The level of compression varies with the type of data being compressed;
zipped text documents can be as small as 4 or 5% of the size of the original
source files, but since movies and images are already compressed, they??™ll
only compress to 95 to 98% of their original size, if that.
This compression makes ZIP files great for sending over the
Internet, since smaller files can be sent faster. The ZIP
archive format also has built-in error checking, so if you find
that certain files are getting corrupted when you email them
or send them through a web site, try zipping them up to
???protect??? them.
To open a ZIP file, just double-click it. You can extract files from ZIP
archives by dragging them out of the ZIP folder window. You can also rightclick
a ZIP file and select Extract All, but you??™ll have to deal with a more
cumbersome wizard interface.

Create a new ZIP file by right-clicking on an empty portion of the desktop or
any open folder, and selecting New ??? Compressed (zipped) folder. (The
name here is actually misleading, since ZIP archives are actually files and not
folders.) Then, add files or folders to the ZIP by simply dragging them onto
the icon or the open ZIP window.
Another way to do this is to right-click a folder or a group of files, select
Send To, and then select Compressed (zipped) folder. This is especially
convenient, as there??™s no wizard or other interface to get in the way: if you
send the CompuGlobalHyperMegaNet folder to a ZIP file, Windows compresses
the folder??™s contents into a new CompuGlobalHyperMegaNet.
