VirtualBox does not offer their Guest Additions for Windows 98SE, which means one does not have access to file sharing between the Host operating system and the Virtual Guest. The way to solve this is to set up a virtual network between the Host operating system and the Guest Operating system. I just went through this rather arduous procedure, and have written a sort of "How-To" that I am willing to share with anyone interested. Send me a PM with your e-mail address, and I will forward a copy of the document.
