The directories are accessible from the command line or from batch files; I use them to provide a secure haven for a communcations front-end (FrontDoor 1.99/2.0) system files, to prevent inadvertant fiddling which might bring the (automated) mail system down. The software recognizes it (FrontDoor) and MS-DOS 4.01 does as well. What sort of problems have you experienced using ALT-255 with 4.01?
