I remember a version of DOS too that had this feature.
Anyway, mounting a 2nd partition / disk in an empty directory (folder) 
like a UNIX file system can only do is actually built in on Win2K and XP 
(and an option in NT4.0).

Scroll down to
*16. Mount a new hard drive as a folder in your C: drive*

As far as Windows is concerned, a drive mounted as a directory is just a 
directory, so no extra drive letters are involved. This can also cut 
down on storage confusion for the average user, and it's easy to do, 
though it can /only be done with NTFS/ /formatted partitions,/ and 
obviously the boot partition cannot be used this way, though other 
partitions can be added to the boot partition.


I had to google for it as I couldn't rememeber. The DOS equivalent 
(oddly not in 6.22) might have been "join". I remember my 1st upgrade to 
a DOS with directories (2.11 or 3.3, can't remember), back then we set 
"switch char"  to - instead of / which meant the newfangled Path char 
was / instead of  \  Later they removed that from DOS. (We already using 
UNIX and Cromenco Cromix then in work)

It's in Disk Manager.

This is less fatal than striping without parity or mirrors if one disk 
fails and works with existing files as long as you have NTFS.
