How to Check Disk Space PowerShell on Windows 10/11

Now, I believe that you already have known all the PowerShell disk space check cmdlets. Let’s see how to let PowerShell check disk space using these cmdlets on Windows 10/11.

Way 1. PowerShell Get Disk Space via the Get-Volume Command

The first and simplest method for the “PowerShell get free disk space” operation is to use the Get-Volume command. Here we summarize 2 common examples as follows.

# 1. Show All Drives and Space Allocation on the Computer

To do this work, you just need to open the PowerShell window by pressing Win + R to open the Run box, typing powershell in it, and pressing Enter. Then type the following command in PowerShell and hit Enter.

Get-Volume

Now, you should find a list of drives and their information, including free disk space and total disk space on the local computer.

# 2. PowerShell Free Disk Space for a Specified Drive

If you want to get free disk space for a particular drive like C, you can run the following command in PowerShell. Here you can replace C with other drive letters that you want to check.

Get-Volume -DriveLetter C

Way 2. PowerShell Get Disk Space via the Get-PSDrive Command

Another simple way is to use the Get-PSDrive PowerShell disk usage check cmdlet. Here’s how to use this cmdlet.

# 1. Show Free Disk Space for All Drives on the Computer

If you want to know the free disk space of all drives in GB, you can directly run the Get-PSDrive cmdlet in PowerShell. Once run, you can view the used/free disk space, provider, and root for all drives.

Get-PSDrive

# 2. Show Free Space for a Particular Drive

To get the used/free disk space for a specified drive, you just need to run Get-PSDrive + drive letter command. Here we take C drive for example.

Get-PSDrive C

Way 3. PowerShell Get Disk Space via the Get-WmiObject Command

If you want to get the all information about your logical drives, the Get-WmiObject plus Win32_logicalDisk PowerShell script is a good choice. Here’s how to use this cmdlet.

# 1. Show Free Space for All Drives on the Local Computer

Type the following command and hit Enter. Then you will get the total and free space of all drives in GB.

Get-WmiObject -Class win32_logicaldisk | Format-Table DeviceId, MediaType, @{n="Size";e={[math]::Round($_.Size/1GB,2)}},@{n="FreeSpace";e={[math]::Round($_.FreeSpace/1GB,2)}}

Also, you can run the following command to get free/total disk space and the free percentage of each drive on the local computer.

Get-WmiObject -Class Win32_LogicalDisk |

Select-Object -Property DeviceID, VolumeName, @{Label='FreeSpace (Gb)'; expression={($_.FreeSpace/1GB).ToString('F2')}},

@{Label='Total (Gb)'; expression={($_.Size/1GB).ToString('F2')}},

@{label='FreePercent'; expression={[Math]::Round(($_.freespace / $_.size) * 100, 2)}}|ft

# 2. Check Free Disk Space on Remote Computers

If you want to know the total free disk space on the remote computers, you can also use the Get-WmiObject cmdlet. Here you need to replace the computer name according to the actual situation.

Get-WmiObject -Class Win32_logicalDisk -ComputerName srv01,srv02,srv03

Way 4. PowerShell Get Disk Space via the Get-CimInstance Command

In addition, the Get-CimInstance cmdlet can help you check free disk space on both local and remote computers.

# 1. Show Free Disk Space of All Drives on a Local Computer

To get the total/free disk space of all drives on a local computer, you can run the following command in PowerShell.

Get-CimInstance -Class win32_logicaldisk | Format-Table DeviceId, MediaType, @{n="Size";e={[math]::Round($_.Size/1GB,2)}},@{n="FreeSpace";e={[math]::Round($_.FreeSpace/1GB,2)}}

Also, you can run the following command to know more information about the drives such as free percentages.

Get-CimInstance -Class Win32_LogicalDisk |
Select-Object -Property DeviceID, VolumeName, @{Label='FreeSpace (Gb)'; expression={($_.FreeSpace/1GB).ToString('F2')}},
@{Label='Total (Gb)'; expression={($_.Size/1GB).ToString('F2')}},
@{label='FreePercent'; expression={[Math]::Round(($_.freespace / $_.size) * 100, 2)}}|ft

# 2. Get Free Disk Space on Remote Computers

If you want to total/free space of a particular drive like C on remote computers, you can run the following command in PowerShell. Here you need to replace the computer name and drive letter according to your needs.

Get-CimInstance -ComputerName computername win32_logicaldisk | where caption -eq "C:" | foreach-object {write " $($_.caption) $('{0:N2}' -f ($_.Size/1gb)) GB total, $('{0:N2}' -f ($_.FreeSpace/1gb)) GB free "}
