In this video I’ll show you how you can see all the folder sizes in a folder. Windows by default only lets you see a file size column, not folder size column. So I’ll show a lightweight free program that should do the trick!
One thing I forgot to mention (duh) is if you click the ‘Size’ column in FolderSize, it will arrange by size.
