>I have not tried it, but what happens when a tool such as WinZip (32 bit version) tries to create a zip greater than 2G? I would suspect that the problem is with 32-bit and the ability to access files greater than 2G in size (2**32). If this is the case then you will have to use a shell command and a 64-bit version of a zip compressor to create the zip archive file that is greater than 2G. You cannot call any active-x component that is 32-bit to create files greater than 2G.

32 bits is 4G, not 2G.
