GetFoldersize does a simple thing: it display the size of your files and folders. It manages to make this simple but extremely useful function not only quick and easy but also highly flexible. It's freeware from Michael Thummerer Software Design.
GetFoldersize has a three-part, draggable, and easily resized interface, with a left-hand Folders panel and a split view on the right, Drives above Files, that could be displayed and hidden via toolbar icons. In fact, most of this program's options are available right on the toolbar, including font size, interface language, columns, icon labels and size, and units in bytes through gigabytes, with or without decimal places. This makes sense since the program's sole purpose is to display the size of your stuff on disk. We clicked New and browsed to a directory on our C drive, and then clicked the Scan button. GetFoldersize's developers say their algorithms scan systems quickly, and it did so to ours, displaying a tree view in the Folders panel and our selected directory in the Files panel. We could order files or folders by size, path, extension, type, attributes, and dates modified, created, and accessed, and preview files in the customizable view; right-clicking individual files called up a well-filled context menu. To say that GetFoldersize does nothing but display folders and files isn't quite correct, since we could delete files singly or in batches. Sure, it's a pretty basic function, but the ability to preview and delete files as you're sorting through them without having to select and delete them in Explorer certainly saves time. The Search feature helped us track down some MIA files, but this program's chief value is showing you the size of your files and folders, which is invaluable for cleaning out those files and folders you don't want, don't need, and don't even know what the heck they're doing up there in your PC's attic anyway. Using it, we quickly found a catalog of JPEGs that some uninstalled software had left behind and deleted them.
GetFoldersize extracts and presents useful information about your system and presents it in an easily customized view that beats Explorer, in our view.
