WinDirStat alternative

This post from MiniTool Partition Wizard introduces several WinDirStat alternatives. All of them can help you figure out what is taking up your disk space. You can read this post and choose the one you prefer to have a try. Don’t worry about the cost, as most of them are free.

Quick Navigation :

With the usage of a hard drive, the disk space will run out gradually if you don’t clean it up. Then you will be unable to store more files. Even worse, your PC may slow down. Fortunately, there are some tools you can use to free up disk space. WinDirStat is such a tool.

WinDirStat, available on Microsoft Windows, is a free and open-source tool for disk usage analysis. This tool was first released in 2003 and has a history of about 17 years. With this tool, users can figure out what is taking up space on a drive, or in a folder. And the analyzing result displays with a colorful graphical display (a treemap), as the following picture shows.

It is useful. However, some users don’t like its user interface. If you are one of them, you can consider the following WinDirStat alternatives. They have similar features but with some differences. Let’s see them one by one.

Warning: Be careful if you decide to delete a file after analyzing the disk space. If you delete system files mistakenly, your computer may run into problems.

WinDirStat Alternative 1: MiniTool Partition Wizard

The first WinDirStat alternative I want to introduce is MiniTool Partition Wizard, a disk management tool for Windows. The Space Analyzer feature is embedded in this tool and it enables users to scan a hard drive and check the hard drive space usage for free. How to use this tool? Here is the tutorial:

On top of the Space Analyzer page, you can check the Total Space, Space Used, and Space Free of the selected drive. In the scanning result, Space Analyzer offers three ways to view the files and folders stored on the drive: Tree View, File View, and Folder View. You can choose one according to your needs.

To find large files, you can click Size and view these items in descending order. Right-click each item, and you will get more options.
