Folder Size is a powerful FREE utility that can analyze your computer and display all the file and folder sizes. You can easily check the distribution of your disk space as the tool will provide detailed information on the file and folder sizes including their subfolders.
The Explorer-style interface is very intuitive and easy to use. Folder Size will display the folder tree on the left and the size of the folders and the files in a neat table on the right. You can also see the percentage of the file or folder size compared to its parent. The results can be sorted via different criterion so you can sort them by folder size in order to find the largest items.
