Which folders use up the most space? FolderUsage is a simple tool to analyze the content of a folder structure in order to find the files and folders that take up the most space. Simply select the root folder and the program will analyze its content and create a report that shows all subfolders and their content sorted by size. You can also configure filters that limit the reporting to files based on their file date and/or size, or by Regular Expression. Copyright Snapfiles.com
