What size are the .WBD files when doing a real-time transfer over the Internet?
Not to be vague, but the size of the .WBD file depends on the size of the drawing you are doing. The initial size of a blank .WBD file is approximately 70KB. Typical file sizes for 10 snapshots range less than 150K. Files can grow to several MB if you use the board for many days and put all of that activity into the same .WBD file. In addition, with the 1.5 Professional Series software, you can embed .WMF overlays into your file. Your file size can grow quite large depending on the complexity of the .WMF overlays.
