Check available Disk Space on Windows devices

Low disk space is a silent productivity killer. To ensure critical updates and resources deploy smoothly, IT admins must proactively monitor and manage storage, preventing disks from choking on unnecessary data.

The following PowerShell script helps the IT Admins to remotely get the details about the disk space from their managed Windows devices.

1. Create a file on your desktop, for example, check_available_disk_space.ps1 and open it in a text editor like notepad++

2. Copy the contents below to the file or click here to download the file.
   

   # Get information about drive name, available space, used space, and percentage of free space for all drives
   $drives = Get-WmiObject Win32_LogicalDisk |
       Select-Object DeviceID, VolumeName, @{Name="TotalSpace(GB)"; Expression={[math]::Round($_.Size / 1GB, 2)}}, @{Name="FreeSpace(GB)"; Expression={[math]::Round($_.FreeSpace / 1GB, 2)}}
   
   foreach ($drive in $drives) {
       $usedSpace = $drive.'TotalSpace(GB)' - $drive.'FreeSpace(GB)'
       $percentageFree = ($drive.'FreeSpace(GB)' / $drive.'TotalSpace(GB)') * 100
   
       [PSCustomObject]@{
           "Drive Name" = $drive.DeviceID
           "Available Space(GB)" = $drive.'FreeSpace(GB)'
           "Used Space(GB)" = $usedSpace
           "Percentage Free" = "{0:N2}%" -f $percentageFree
       }
   }
