I do not think this is a DZ issue because I see this in WinZip also. This depends on a folder setting. In Explorer, click on View/Folder Options. Click the View tab. Uncheck the Allow All Uppercase Names box. Now do a test with DZ and WinZip. Both produce the same results whether that box is checked or not.
