WinDirStat Portable lets you view a detailed overview of disk usage statistics and identify any unnecessary files that may be taking up valuable space on your computer. Installer is also available.

With its intuitive and easy-to-use interface, WinDirStat Portable presents a clear and detailed breakdown of your disk usage, showing you which folders and files are taking up the most space. This process allows you to quickly and easily identify any areas where you can free up space, enabling you to optimize your computer's performance and improve its overall efficiency.

On start-up, WinDirStat Portable reads the whole directory tree once and then presents it from three useful views:

The directory list, which resembles the tree view of Windows Explorer but is sorted by file/subtree size,

The treemap, which shows the whole contents of the directory tree straight away,

The extension list is a legend and shows statistics about the file types.

WinDirStat Portable's treemap represents each file as a colored rectangle, the area of which is proportional to the file's size. The rectangles are arranged so that directories again make up rectangles containing all their files and subdirectories. So, their area is proportional to the size of the subtrees. The rectangle's color indicates the file type, as shown in the extension list. The cushion shading additionally brings out the directory structure.

Whether you're looking to declutter your hard drive or want to keep a closer eye on your disk usage, WinDirStat Portable is an essential tool for any Microsoft Windows user. It's an older app, but it checks out.
