Have you ever used the DOS command : SUBST ?

Some DOS commands were so important , that it created a base to evolve the future versions of the Windows cult. SUBST – I never used in my 21 years of fiddling with the computer till the time I started using the Storage Services on the cloud. In fact SUBST , is a key behind mapping of network drives. Let’s check what was so special and then make use of it for our daily needs.
SUBST was basically used to substitute paths on physical and logical drives with drive names [virtual drives]. A Microsoft Windows Command prompt displays the following help screen.
C:\>subst /?
Associates a path with a drive letter.
SUBST [drive1: [drive2:]path]
SUBST drive1: /D
  drive1:        Specifies a virtual drive to which you want to assign a path.
  [drive2:]path  Specifies a physical drive and path you want to assign to
                 a virtual drive.
  /D             Deletes a substituted (virtual) drive.
Type SUBST with no parameters to display a list of current virtual drives.

Now, let’s move on to the Visual Dynamics of the same command. Visual SUBST can be downloaded from :
http://www.ntwind.com/software/utilities/visual-subst.html or http://visual-subst.en.softonic.com/.
The installer is of 112 KB and a click is sufficient to make it alive. After installation :

Select a drive letter for the path and click the green button.Here the virtual drive T: has been mapped to C:\Users\Kausik\Google Drive\ .
Click the Red Button to delete the Virtual Drive.

DOS had an undocumented command “TRUENAME” to reveal the true identity of virtual drives.Relevance of SUBST or its Visual Substitute makes a base for mapping network drives by OS derived out of  DOS
So, why an old horse which was rarely ridden becomes a hero at the outset of cloud storage?

Today , all cloud storage solutions sync data from pre-defined folders.

It could be a default or a user defined path. Making virtual drives of such paths helps us to drag and drop files which needs to be a part of the cloud.So, if Google Drive Syncs data stored in C:\Users\Username\Google Drive or Drop Box syncs every bit of C:\Users\Username\Dropbox, show some respect to these paths with a Drive Letter.

I’m sure your work becomes easier and faster.
