This is a really tricky one! The WMI namespace Win32_MountPoint has the info we need to see which drives are mounted as a disk drive or a folder.

The bottom entry is an example of a drive mounted as a folder.

#Use Get-WmiObject Win32_MountPoint if the below fails
PS> Get-CimInstance Win32_MountPoint 


Directory             : Win32_Directory (Name = "H:\")
Volume                : Win32_Volume (DeviceID = "\\?\Volume{38569fb2-42e2-4359-8b42-1807...)
PSComputerName        :
CimClass              : root/cimv2:Win32_MountPoint
CimInstanceProperties : {Directory, Volume}
CimSystemProperties   : Microsoft.Management.Infrastructure.CimSystemProperties

Directory             : Win32_Directory (Name = "C:\thumb")
Volume                : Win32_Volume (DeviceID = "\\?\Volume{e5d29a99-c6c2-11eb-b472-4ccc...)
PSComputerName        :
CimClass              : root/cimv2:Win32_MountPoint
CimInstanceProperties : {Directory, Volume}
CimSystemProperties   : Microsoft.Management.Infrastructure.CimSystemProperties

With this info in mind...we can pass the DeviceID info over to another command to find out how much disk space there is.

get-volume | ? Path -eq  $mount.Volume.DeviceID

DriveLetter FriendlyName FileSystemType DriveType HealthStatus OperationalStatus  SizeRemaining    Size
----------- ------------ -------------- --------- ------------ -----------------  -------------    ----
                         FAT32          Removable Warning      Full Repair Needed       3.44 GB 3.74 GB

Now, let's make this into a function where you pass in the mount path and we return the info on the actual disk.

Function Get-MountedFolderInfo{
    param($MountPath)

    $mount = gcim Win32_MountPoint | where directory -like "*$MountPath*"

    if ($null -eq $mount){
        return "no mounted file found at $MountPath"
    }

    $volumeInfo = get-volume | Where-Object Path -eq $mount.Volume.DeviceID
    
    if ($null -eq $VolumeInfo){
        "Could not retrieve info for:"
        return $mount
    }

    $volumeInfo
}
Get-MountedFolderInfo -MountPath C:\thumb

DriveLetter FriendlyName FileSystemType DriveType HealthStatus OperationalStatus  SizeRemaining    Size
----------- ------------ -------------- --------- ------------ -----------------  -------------    ----
                         FAT32          Removable Warning      Full Repair Needed       3.44 GB 3.74 GB
