Using WMI to get mount point from volume [solved]

[JD2066]

Hi,

I'm trying to find the mount point a volume has with WMI.

I have the following code to list the volumes and mount points but it doesn't seem to work right.

$WMIService = ObjGet("winmgmts:\\.\root\cimv2")
$WMIMountPoints = $WMIService.ExecQuery("Select * from Win32_MountPoint")
If IsObj($WMIMountPoints) Then
    For $MountPoint in $WMIMountPoints
        MsgBox(0, "WMI Info", $MountPoint.Volume & @CRLF & $MountPoint.Directory)
    Next
EndIf

I would expect the output of $MountPoint.Directory for the C: drive to be C:\ but it's not, the value is Win32_Directory.Name="C:\\".

Anyone know what the problem is?

Don't know how WMI regularly returns path strings, but if you export a registry key

to a .reg file it will also return most path strings this way.

Probably for easy processing by the system, '\' being the C++ escape character ?

I just found the solution.

The following code works just fine:

$WMIService = ObjGet("winmgmts:\\.\root\cimv2")
$WMIVolumes = $WMIService.ExecQuery("Select * from Win32_Volume")
If IsObj($WMIVolumes) Then
    For $Volume in $WMIVolumes
        MsgBox(0, "WMI Info", $Volume.Name & @CRLF & $Volume.DeviceID)
    Next
EndIf

I just found using Win32_Volume instead of Win32_MountPoints returns the correct values.

I had assumed before posting that Win32_Volume didn't list MountPoints.

Not sure why I didn't think to check before posting.

@all

Win32_Volume -> Windows XP and earlier: This class is not available.
