This program was created by Tara Piccari, as a part of the Aria's Creations common code library as a helper utility.
|

Aria's Creations is a alias for online-only works. Aria is an anagram derived from my name. piccARI, tarA. You place my last name first, take the last 3, skip the first 3 in my first name and take the remaining character(s) and you have my alias.

|

This utility analyzed the specified folder path to generate a detailed report of directory and file sizes as seen below.
