The freeware can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders in an Explorer-like fashion. Large folders can be identified at a glance thanks to the gradient bar displayed in the background. All scan results can be drilled down to file level and filters, e.g. for files of a certain type, can be applied.

The user interface of the software consists of a standard window with files displayed in treeview mode, in descending order (according to their size). If you hover the mouse cursor over a particular file, you can view its size, permissions, folder, date of creation and last modification, allocated size, path length, number of size, full path, directory level, owner, and more.

It scans network drives and locally synchronized cloud shares (except on Windows servers and within a Windows domain) – just like TreeSize Personal!  The column view presents more detailed information for each file and folder. Here you will find the size or number of files as well as the last access date and the owner (and other useful facts). Scan results can be broken down with the flexible filter feature. You can use the filters, for example, to find files of a certain type, such as temporary files, text files or images and use this information to clean up your hard disks.
