It’s a nice and light tool to view the folder structure of the drive showing how much storage is consumed. This can get in handy when you have storage problem and don’t know which folder is using the most storage.

“TreeSize Free can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders. Expand folders in an Explorer-like fashion and see the size of every subfolder. All results can also be drilled down to the file level. Scanning operations run in a thread, so you can already see results while TreeSize Free is working. The Explorer context menu is supported within TreeSize, as well as the usual drag & drop operations.”
