Minh's Free DiskSpaceExplorer is a simple freeware utility that scans an entire hard disk and provides size-related information for each folder and its subfolders. This will allow you to quickly identify which folders take up the most hard disk space. After the disk scan, the program will provide you with the number of bytes, files, and folders that currently occupy a given folder (and its subfolders). You then have the opportunity to immediately delete a given folder (and move it it to the recycle bin).
