question

Hi @KedarTamboli-6326,

Mathematical operations are not supported in WMI, so FREESPACE/SIZE <= '0.1' can not be used.

We could use wbemtest to see if the WMI query is correct. Here is the result of this query:

So we could use powershell script to achieve it. Here is the powershell, kindly refer to it:

 $DiskCount = ((Get-WmiObject -Class Win32_DiskDrive).Caption).count
 $DiskInfo = Get-WmiObject -Class Win32_LogicalDisk 
 echo "--------------------Statistics disk partition status-------------------------"
 echo "    Drive letter    Free space   Remaining proportions"        
 foreach ($Drivers in $DiskInfo) 
 {
     $PartitionID = $Drivers.DeviceID
         if ($PartitionID -eq 'c:'){
             $PartitionSize = "{0:N2}GB" -f ($Drivers.Size/1GB)
             $PartitionFreeSize = "{0:N2}GB" -f ($Drivers.FreeSpace/1GB)
             $PartitionFree = ($PartitionFreeSize/$PartitionSize)*100
                 if(($PartitionFree -le 10) -or ($PartitionFreeSize/1 -lt 5GB)){
                     echo "    $PartitionID       $PartitionFreeSize    $PartitionFree%" 
                  }
         }
 }
