I need some help, 2 of us use Civil 3d 2020 for work. I have found this to happen, but not completely empty folders, the guy I work with has this issue. When we have a drawing open and we try to open another dwg through the menu bar, file, open then the window pops up and there are no files or folders to select from. We change from folder to folder and still nothing. We have tried the filedia=1 and still nothing, we rebooted the computer, we ran a repair on it, I have gone in and removed the menu bar and recreated it and nothing.Any help would be greatly appreciated!
