Finding Large Files and Folders on a Volume
You want to find files or folders that exceed a certain size on a volume.
Using a graphical user interface
From the Start menu, select Search.
If you are presented with the options for what to search on, click All files and folders.
Click on What size is it?
Select the radio button beside Specify size and enter the size you want to search.
Select additional criteria if necessary and click Search.
Using a command-line interface
The following command finds folders that are greater than 100 MB in size on the D: drive:
> diruse /s /m /q:100 /d d:
/s option causes subdirectories to be
/m option displays disk usage in
/q:100 option causes folders that
are greater than 100 MB to be marked, and the
option displays only folders that exceed the threshold specified by
Use the diskuse command to find files over a certain size. The following command displays files over 100 MB in size on the D: drive:
> diskuse D: /x:104857600 /v /s
/x:104857600 option causes files over
104,857,600 bytes to be displayed and is valid only if you include
/v option (verbose). The
option means subdirectories from the specified path (in this case,
the D: drive) are searched.

If you find that you are running out of space on a volume and want to see what is consuming the most space, you are better off using the diruse command-line solution. With the other solutions, you could search for all files over 100 MB, for example, but a user could have created a bunch of 10 MB MPEG files. Unfortunately, you can't use the Search dialog box or VBScript to search on folder sizes, which leaves diruse as the most appropriate tool in this scenario.
