At the very bottom of the war task page is a remark about winzip not allowing all uppercase directory names.
Winzip has an option allowing all uppercase names (which is off by default!). It can be enabled by: Menu "Options" -> "Configuration", "View" property/tab page, then "General" group box has an option called "Allow all uppercase file names". Ticking/checking that box will cause an immediate refresh of the Winzip file contnt window. Tariq
