You can view and select individual folders from the left menu and analyze their content in the larger right panel. The program works with both local and network files and comes with powerful features to let you know the free and used space from a glance.

You will be happy to learn that all the files are displayed complete with additional details, such as the name, size, space allocated, number of files and folders (in case it’s a directory), the last date it was modified, as well as the type and name of the owner. The information is saved in an XML format and can be reloaded later, therefore allowing you to make comparisons between the folder sizes.
