Unfortunately, so are all of us regarding what kind of computer you are using and what Operating Sysytem (OS)... ???

Anyway, here are links for the three major and best compression applications...


For WinZIP... (.zip)

WinRAR... (.rar)

Stuffit (.sit)...

Read the install and setup info for all of them !
Doing the correct configurations from the very beginning will aid you enormously...

You may also be successful in searching for and downloading trial? versions of all of the above via the Gnutella Network.

And, as murasmae said, be very, very, very cautious of .exe files that you may D/L...
However, one prob with some .exe files is that they are Self-Extracting .zip files - 99.99% harmless !
Self-Extracting .zip files are files that were compressed by someone using a special feature of some WinZIP apps. that allow you to compress a file WITH the Extraction software included in the file... The person receiving the file does NOT need to have the WinZIP software installed in order to open the SE file... Hence they are .exe files......
Complicated and dangerous world out there, huh ?
