Folder Size is designed to analyze your hard drives then display file/folder sizes for easy checking of disk space distribution.
Once you have selected a target area, it displays the folders/files' sizes providing a percentage of the total disk size that they currently occupy. There is also a report that can be easily sorted by identifying the largest folders and files. Having access to the report's details will allow you to quickly discern which files or folders are taking up your drive space. Folder Size will also scan the sizes of all the subfolders as well.
Folder Size can scan your entire hard drive in minutes due to the optimized scan algorithms and then list details on the tree size. It uses a progressive scan, which will allow you to continue the scan from the point of any interruption. You also have the option to scan a single folder so you can save some time.
