There are multiple methods available to check the disk space in PowerShell. This section introduces the three most commonly used ways to check your disk space using PowerShell commands. Comparatively, these are less complicated and functional for Windows users.

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

Get-Volume is the easiest command to find disk storage information. Using this command, you can check the space details of all the volumes at once.

Now, you will find a list of partitions along with their information.

To inquire about the details of a specific drive, such as the C drive, insert the following command: Get-Volume -DriveLetter C. If you want to get the information for another drive, simply replace the drive letter accordingly.

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

It is another effective yet simple way to check disk space using cmdlet. Here are two different commands to follow:

# 1. Check the Space of All Drives

This command displays the free disk space of all drives in GB.

Step 1: Open the PowerShell window.

Step 2: Type Get-PSDrive command, and hit Enter to run it. 

It will display a detailed view of used/free disk space, provider, and root of all partitions in the local drive.

# 2. Check the Space of a Specific Drive

Check the used/free disk space for a particular drive by running the following command: Get-PSDrive C. Replace the latter of the target drive instead of C.

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

This method is a slightly complicated but practical alternative compared to the earlier-mentioned methods. It provides detailed information about your drives. Two scripts of this method provide detailed information, including media type, drive's total size in GB, and employed/free space. 

1) Check Total Allocated Space

Select the following command, copy and paste it into PowerShell, and hit Enter. 

• 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)}}

See the displayed details. You can easily determine the space allocation of all partitions of the local drive.

2) Check the Storage Capacity Assigned to Each Drive

Run the following command to check the detailed space portion of each drive specifically. It shows free/total disk space and the free percentage of each drive in your computer. 

All you need to do is drag and drop the given command on PowerShell. See the screenshot to know how it works.

• 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
