Diskitude

The File Explorer found in Windows is the basic navigation method through your storage devices, offering clear view of all files and folders. There are also various third-party alternatives you can use for enhanced analysis, which might offer more insight on folder size, especially since File Explorer doesn’t display it. A suitable analysis tool here is Diskitude.

Build a folder view from a source drive or directory

Setup is the first step to get the application running. However, you need to make sure that .NET Framework is on your computer, but there’s a high chance it’s already there, especially since it usually comes in the default Windows set of features.
As far as the visual design is concerned, the application keeps things rather simple, in the sense that there are no outstanding textures or effects. On the other hand, things are incredibly clear, and folder representation updates in real-time as the program scans the target directory. As such, the first step to get the app ready is to pick a folder or drive of interest, and this is done through the browse dialog which pops up on launch.

View size values and navigate through content

The directory structure is built around a core circle representing the source directory. Multiple pieces are attached to it, letting you cleverly visualize the entire structure of directories and subdirectories. Hovering the cursor over a section displays the total size, as well as path of the folder.
Hitting F5 refreshes the view, which is helpful in case changes are made in the meantime. The structure is interactive, with different actions for both mouse buttons. The left button opens the directory in File Explorer, while a right click builds a new view around the selected directory.

A few last words

Bottom line is that Diskitude is sure to come in handy if you want to tidy up your PC, or simply get a view of size distribution across folders. It instantly builds a cool representation of directories, while also offering navigation and valuable size info.
