What is the DiskUsage tool in Windows 10

Windows 10 has a built-in disk space analysis tool called DiskUsage (diskusage.exe). The new micro-application is available in pre-release builds, starting with build 21277.

Τα Windows 10 Build 21277 είναι μια στο Dev Channel και για πρώτη φορά φέρνει στα Windows ένα βοηθητικό πρόγραμμα ανάλυσης χώρου στο δίσκο μέσω της γραμμής εντολών.
Αυτή η εφαρμογή μπορεί να σαρώσει τους φακέλους σας ή ακόμη και ολόκληρη τη μονάδα και να εμφανίσει τον χρησιμοποιημένο χώρο από κάθε φάκελο.

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 particular one .

Finally, the application allows the creation of a settings file that will keep the defaults for the options you want to always use with the application, e.g. the /h switch. You can also customize them which returns to block certain files and folders from being edited.

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.
