The DOS SUBST command is a very powerful tool, even in Windows. It allows you to
use a single (available) drive letter to specify a path which could be any number
of folders deep, e.g. "c:\folder1\folder2\folder 3....\foldern" (we've tested it
to 15 levels). Virtual Drive Creator™ (VDC) does exactly the same thing.
Creating and Removing a Virtual Drive
Select a letter in the “Available Virtual Drive Letters” list. You can use the cursor
keys to select your letter or Click the letter with your left mouse button. You can
then, using the Drive and Folder Lists, browse to the folder you want set to the
selected Virtual Drive letter. Click the “Add Virtual Drive” button to set the virtual
drive for this session. Click the “Make Permanent” button to make the virtual drive
permanent. Or, Click the Cancel button to abort the operation.
You can also input the full path first, then Double Click on the letter. This will
create your virtual drive while bypassing the “Add Virtual Drive” button. Be sure
of the full path before Double Clicking the letter!
To remove a virtual drive, select the letter of the virtual drive you want to remove
in the “Used Drive Letters” list. As with creating a virtual drive, you may use a
combination of your left mouse button and the cursor keys to select the letter of
the virtual drive you want removed. Then Click on the “Remove Virtual Drive” button.
You can also Double Click the letter to remove its’ virtual drive.
Drive letters in upper case (A:) are fixed (hard) drives, removable drives with or
without media in their respective drive bays or drives that have been "Virtualized".
The drive letters in lower case (b:) are Network drives, not available to VDC.
Virtual drives are discarded when you reboot your computer, unless they have been
Why use VDC?
Suppose you are working on a project like the RPN Engineering Calculator™, and all
your files are in a Folder named "C:\Program Files\Microsoft Visual Studio\VB98\RPN
Calc", to access your files in Explorer, or VB6 you need to traverse through the
maze of folders to get there. Using VDC I choose the letter R to represent that particular
path and in any explorer type directory tree the letter R is there showing me all
of my Folders and files I have in that Virtual Drive. I can also access that directory
from a DOS Window.
Special for CD-ROM users! This works great! Copy the contents of your CD to a folder
on you hard drive, not the root. Create a virtual drive pointing to that folder.
Install the CD using the virtual drive letter. And like magic you can run the CD
from your hard drive. This work for about 70% of the CDs we've tested, it does not
work for music CDs or Data CDs.
What does it cost?
Virtual Drive Creator™ (basic) is free. Virtual Drive Creator™ - Pro sells for $19.95.
They only difference between the basic and Pro versions is the Pro version will offer
the option to make the virtual drive permanent and the basic version will test your
system to see if it is capable of performing the required instruction to make the
virtual drive permanent.
What this all means is when you download and use VDC there will be no time limit,
nor will you be nagged to purchase the Pro version (the "Buy Now" buttons are not
nags, they are there for your convenience).

How to get VDC

A note about the download file: Since most computers have all of the required Microsoft®
files already installed we have eliminated them from our standard download file to
reduce it to less than 35 percent of the original size. If you find that after installing
VDC there are some missing files, download the full package, vdcx-max.exe or vdc-max.zip
download the missing files package: MS_reqd.exe or MS_reqd.zip and run the setup
file to install the missing Microsoft® files.
