Zip Files upload failed

I try to upload a zip file to WebExplorer Server demo but failed why?

WebExplorer Server supports online zip or unzip?

Online zip/unzip is not supported but it is a feature to be added soon. The demo works as expected, maybe some visitor had selected an unsupported upload plugin by the time you had been testing.

This is a feature -- online unzipping of files -- that would be very useful to us, too.  Please let me know when/if there is an update for this.

Thanks, Courtney
