Hello, this is Dr. Bill.
Welcome back.

One of the most things that someone in 
information systems needs to learn is 
task automation.  Automatically performing
the same task over and over again.
If you were to step in my office, and watch me
work for a few hours - you are going to surprised
at how frequently I use sometype of programming script
to perform a repetitive task.  Not only saving time,
but creating less errors.

Task automation can be accomplished using a scripting environment
like PowerShell or even a programing language like
Visual Basic.  

To really make task automation powerful, it needs to be recursive.
This means the code can call itself.  In other words, it recursively look through 
folders, and sub-folders within those folders, and sub-folders
within those sub-folders, and so on.

To illustrate task automation, we will Powershell and then
look at a simple example using VBA.
