If you use an ActiveX-capable browser (e.g., MS Internet Explorer 4.0 or better), you can subscribe to an ActiveX extension that enables you to upload files by 'drag & drop'. A specific icon will be placed prominently in the headers of your Folder pages. Just drop a file on this icon to upload it to the current Folder or Meeting. The extension also uploads groups of files -- a feature not provided by the standard file upload function of the browsers.
If you plan to use this option,
Use ActiveX-enhanced interface
to enhance your Folder pages with ActiveX-based functionality.
