This is a little function I wrote one day when I needed to get the total size of a set of folders (including sub folders). It performs a recursive search and computes the total count and also shows the size in a more human-readable format. It also have a “hidden” property called SizeInBytes that can be helpful if you want to do size calculations and need the size in a common format.
Enjoy.
