Elizabeth asked this week:
“Hi Steve, I have been using the free version of Network Administrator for quite a while and I really like it. I was wondering, is there any way you could use this to show me the percentage and amount of space that is free on the C drive of computers on my network?”
Great question Elizabeth.
We created a plugin that does exactly what you want. You can point it at any machine(s) you are interested in and let it rip:
You can tell it to just show you the free space on the C Drive, or all drives:
Network Administrator is a free download (Works on up to 3 computers at once). Get it from our download page.
What if you want to get this info on your own, using a script?
Let us see what VB Script can do for us.
Set sWMI = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\.\root\cimv2")
Set sDisks = sWMI.ExecQuery ("Select * from Win32_LogicalDisk Where DeviceID = 'C:'")
For Each sDisk in sDisks
iFreeSpace = sDisk.FreeSpace
WScript.Echo sDisk.DeviceID & " - " & sDisk.FreeSpace & " Bytes Free" & vbCrlf
Next
The above script runs a query to find the C Drive, and get information about it.
It will show us how many bytes are free:
What about all hard drives? If we make a slight change to our WMI query we can get all of them (The change is in bold):
Set sDisks = sWMI.ExecQuery ("Select * from Win32_LogicalDisk Where DriveType = 3")
Now, it shows the free space on all three hard drives on my computer:
You could get the info remotely by using our free remote execute tool. If you saved your script as free.vbs, calling it would look like this:
RemoteExecute.exe -q -c -h 10.10.10.1 -u user -p password c:\SomeFolder\Free.vbs
Put one of these for each IP you want to check in a bat file and you could get a quick look at your drive space across your network.

Hi Steve,
I am so happy you guys made this plugin! I just purchased a copy. It is worth the $$. Thanks again for the great support, before I was even a customer 🙂
Great addition to NA Steve. Thanks a ton.
Awesome Steve. Just got the upgrade notification too, I purchased last year. Thanks to you and the team for all the great updates.
Put the VBS script in a shared folder and you don’t need to copy it to each computer’s “C:\SomeFolder” … assuming a common “user” and “password” across the network, you could even scan and log the whole shebang using one command like this:
for /L %%a in (1,1,255) do RemoteExecute.exe -q -c -h 192.168.1.%%a -u user -p password \\Server\SharedUtils\Free.vbs >> c:\User\Public\Documents\Logs\FreeSpace_%date:~4,2%-%date:~7,2%-%date:~10,4%.log
Awesome tip Angus. Thanks for the post
Thanks for this tool steve, it is exactly what I have been looking for. Just a simple way to take a peek and see how much drive space I have free on all of my servers
Getting error message only on the free drive space feature. Logon failure: unknown user name or bad password.
Hello Osvaldo,
Got your email. I think this is a bug, and I will update this post when we get the issue resolved.
Hi Everyone,
This was a bug with our remote execute engine. It was not properly passing the domain information. If you are still having this issue, please get the latest version from our download page. The build number in the top right should end with 155 or greater.
