by admin on February 11, 2012

Windows does not have any in-built command(Like the Linux command du) which show the disk usage statistics for a directory. However, there’s a downloadable tools from SysInternals(now part of Microsoft) which can show us the disk usage numbers.

Du.exe version 1.4 can be downloaded from the below link.
