YuDisk is a disk usage viewer for Windows that helps you inspect how local drive space is being used.
It links an Explorer-style tree with top files and top folders ranked by size, so you can quickly reach the locations using the most disk space. On NTFS drives, YuDisk can use a faster scan mode when launched with administrator privileges.

Standard Scan
YuDisk also works without administrator privileges and on non-NTFS drives by using a normal directory walk.
