ZipX is a powerful and easy to use file concentration and encryption utility for Microsoft Windows. It sustains extraction of files from many different archive formats, and can create both Zip and CAB archives. ZipX is compatible with both WinZip and PKZip and many other popular archive programs. However, some of ZipXs features are quite advanced and might produce zip files that cannot be extracted in other archive utilities.
For example, the use of digital certificates for encryption means that apart from ZipX, only PKWAREs SecureZip will be able to extract files from these archives. ZipX also sustains WinZips new PPMd concentration method. This method, being relatively new, may not be sustained by other archive programs (apart from WinZip, of course). It gives very good concentration, albeit at a much slower speed than the standard Deflate algorithm.
But the choice is yours. You dont have to use the advanced capabilities if all you want to do is generate a simple zip file that can be read by any zip utility.
