(MFC) Iterate over Files and Directories in Filesystem Directory Tree

Demonstrates how to use the Chilkat DirTree object/class to iterate over the names of files and sub-directories in a directory tree.

This example iterates over a directory tree that contains these files and sub-directories:

a
    images (sub-directory)
        dudeA.gif
        Thumbs.db
    hamlet.xml
    pigs.xml
    Setup.exe
b
    yyy (sub-directory)
    zzz (sub-directory)
        HelloWorld123.txt
        test123.txt
    dude.gif
    dudeC.gif
    hello.txt
    Thumbs.db
test123.txt
The output for the code below looks like this:
(sub-directory)
Relative Path: a
Absolute Path: c:\temp\abc123\a
Absolute UNC Path: \\?\c:\temp\abc123\a
----
(sub-directory)
