What does `dir/s` do you know?
Know?
Then, if there is a hidden directory, can the above command list it out?
If you type this command under win98, the result is obviously not possible.
However, we can just modify command.com~
Open command.com (of course, using a hex editor)
Locate to: offset at A348H
Change 10 to 16
Save and exit.
Reload command.com
Try `dir/s`~



Well, I've remembered it.
