Thanks for the kind reply, Andrew!
OK, here's my first impression of WebDAV: I couldn't imagine it. I could follow the instructions, but I made lots of mistakes because I wasn't sure of what I was doing. Maybe I don't work enough on a network to know this intuitively. Maybe my writing a brief tutorial might help us analyze the user's problem. Let me see how I might conceive of it and ask others if this makes sense.
WebDAV is a nifty tool that allows you to drag and drop files from the Dotlrn server to the Windows desktop on your own PC, and back again, much as you likely already do with Windows Explorer. If you like to organize your files by creating new folders and dragging and dropping files and folders, you'll like WebDAV: it works just like Windows Explorer, and it has been designed to look and feel like just one more folder on your network.
To use this tool, you have first to establish a connection to each storage folder on the Dotlrn server that interests you. Since you may want to do this often, we've made it as simple as clicking a bookmark in your browser: clicking this bookmark will cause Windows to open up an Explorer window on your desktop as if the file storage on the Dotlrn server were just one more network resource at your disposal -- which, of course, it will soon become. From there, you have only to drag and drop files and folders from this Explorer window to your desktop or Windows Explorer showing your file system and back again.
Creating this link is basically the same as creating a shortcut to a file. Move your cursor to the icon below, right click ...
Here's a screenshot I made to illustrate.
