Using DiskUse.exe, I have scripted UserSpace.bat to report the total disk space that each user consumes on a set of file system objects that you specify.

The syntax for using UserSpace.bat is:

UserSpace ReportFile Object1 \[object2 ... objectN\]

Where:

<b>ReportFile</b> is the file that will receive the output, in the <b>CSV</b> format of <b>"User","<Space Used>"</b>.
<b>Object</b><i>X</i>    is a file system object, like <b>C:</b> or <b>\\ComputerName\C$</b> or <b>\\ComputerName\ShareName</b>.
NOTE: Other scripts that use DiskUse.exe are:

UserSpace.bat contains:
