If your hard drive is filling up really quickly and you wonder what might be taking up your space, disk analyzers can help you identify the waste space and a way of cleaning up the space. Disk analyzers scan your hard drive and provide detailed information in graphical form of everything using your disk space.
There are plenty of disk analyzer tools available for Windows that mainly differ in their speed while analyzing the disk, Features, and probably License. Some of the Disk Space Analyzers available for the Windows platform include; WizTree, WinDirStat, Disk Savvy, JDisk Report, SpaceSniffer, etc.


WizTree is a fast disk analyzer utility for Windows. It scans your hard drive to show you files and folders using the most disk space. WizTree quickly displays the information graphically of the files and folders using the most space on your hard drive and gives you an option of removing the files.

WizTree is free for personal use but can be used commercially by purchasing a “Supporter Code” while large organizations purchase an Enterprise license for unlimited use. It supports multiple file systems supported by windows including NTFS, FAT, and FAT32. Smartphones and cameras with MTP/PTP can be scanned using WizTree when connected via USB.
