I have not had much time to test it, so be carefull if you try it. I have been able to hide directories by hiding an entire drive. This has worked on a Zenith Z-248, I'm not sure how well it will work on other systems. My procedure is as follows: 1. use dsksetup to change the partition assingment flag to manual 2. use part to create a new partition to hold the data you wish to hide 3. re-boot the system 4. use asgnpart to assign the new partition to the next available drive 5. copy all of the file you with to hide to the new drive 6. re-boot the system When you boot the system with the partition assingment flag set to manual, DOS (at least it does on the Zenith, DOS 3.3) will only assign the first partition of the drive, and will not assign any other partitions. If you try to access the "hidden" drive, you will get a "drive not valid" or similar error message. To access the "hidden" drive, use asgnpart to assign that partition to the next available drive, and then you will have access to the "hidden" data. Chances are that if anyone can figure out what you have done, there will not be any way to prevent them from finding the files. DISCLAMER: I HAVE ONLY EXPERIMENTED WITH THIS METHOD A FEW TIMES. THERE MAY BE SOME HIDDEN SIDE EFECTS OR DANGERS, SO USE WITH CAUTION. -- +-----------------------+---------------------------------------------------+ | Duane L.
