Free Space or Mount Points

I had a question about getting free space of mount points on a windows server. The user had some Exchange servers with a huge chunk of san disk attached. Then he mounted drive letters into empty folders on that disk. This gave him multiple mount points on that one volume. Now he wants to be able to report on each mount point individually. I do not have any servers that have been set up this way and I am out of the office all week. I did find this post in anther forum though.

PS C:\WINDOWS> gwmi win32_volume|where-object {$_.filesystem -match “ntfs”}|ft name,capacity,freespace

name capacity freespace

—- ——– ———

C:\ 20973137920 12781355008

D:\ 88266911744 30121046016

E:\ 36410552320 11617628160

D:\Mounts\D02\ 1924139716608 1785309392896

D:\Mounts\D03\ 1099506044928 1016254210048

D:\Data\Shared\D01\ 2186130853888 697559801856

And here is a link to the forum that I found it. I have not attempted this as I do not have any servers with this type of mount point but try it and I hope that it works. I am not sure if it will though since win32_logical disk, I do not think it will report like this. I also know that you can try win32_mountpoint and this will get you a list of all your mounts. You may be able to do some work and math using that to figure out the free space. I will try to set this up once I return to the office and see if I can work something out if this does not work.
