I consider myself very computer savvy but I don't comprehend the Parallels notion of a shared folder. I create a shared folder in Parallels but I can't see it from Windows. Where's my shared folder? I can drag and drop to/from my shared folder but that seems to work even with folders that I don't share. I can use Windows sharing on the Mac side, then map a network drive from the Windows side and use it. But I don't think a shared folder is required to do this. What am I missing?
