How to create a Tree View of the Windows Folder and extract all the file-folder info.

I have removed most of the designer code.  

Brief description of the control's usefulness:
Show All Dir - Shows the Drives in the system.  Corresponds to LoadTreeViewDir function
Create/Append - Appends info to the exisiting file. Corresponds to btnCreate_Click function.


The rest is the TreeView Control event code.
