Older DOSes (i.e., MS-DOS 6.x) are not aware of the LFN API and
therefore are unable to make any use of them. In DR-DOS 7.02+,
only COMMAND.COM is aware of the LFN API -- so, e.g., DIR displays
long filenames, when a DOS LFN driver is loaded, or when DR-DOS
COMMAND.COM is running in a Windows DOS box. But other system
programs (like CHKDSK, etc.) cannot handle LFNs. In MS-DOS 6.x,
you don't have any LFN support, as far as I know, unless you have
a third party command interpreter, like 4DOS -- but you still need
Windows tools for disk maintenance (or you can try some FreeDOS
tools).
