Windows 10 got a built-in disk space analysis tool called DiskUsage (diskusage.exe). The new applet is available in pre-release builds, starting with build 21277.
Windows 10 Build 21277 is a release in the Dev Channel and for the first time brings to Windows a disk space analysis utility over the line orders.
This app can scan your folders or even your entire drive disk and display the used space from each folder.
DiskUsage is located in C: \ Windows \ System32 \ diskusage.exe. Includes a built-in user guide that you can view while running diskusage /? in a command prompt window.
Let's see how it works.
Note: The tool requires administrator privileges, so open a command prompt window with administrator privileges first.
To find folders in C: \ Windows larger than 1 GB, run the command:
diskusage / minFileSize = 1073741824 / hc: \ windows
The number 1073741824 is 1 GB in bytes.
The diskusage application will display all folders larger than 1 GB on the drive. The gadget has some switches for the list of top N folders and files on the drive or in a folder. For example:
diskusage / t = 5 / hc: \ windows - Shows the 5 largest dirs in a specific location.
Finally, the application allows the creation of a archivey settings that will keep the defaults for the options you want to always use with the app, e.g. the /h switch. You can also customize the results it returns to exclude certain files and folders from being processed.
DiskUsage is still under development and still not working properly. However, such a tool was needed in Windows 10. The official announcement will tell us more about the new application.
