PowerShell Script: Find out free disk space from multiple servers

Hi All, this is my very first post on PowerShell Script. Today, I am going to share a script that you can use to find out free disk space from multiple servers. You will have to create a Text file and a PowerShell script to accomplish this.

Let’s begin by creating a Text file. I have setup a folder on my C: Drive called PS_Script (C:\ PS_Script). I created a Text file, ServerNames.txt, and saved it in C:\PS_Script folder.

Use following code to create a PowerShell script and save it as DiskReport.PS1.

#Get Current date
$currdate = (Get-Date).tostring("dd-MM-yyyy")

#Set path for output file
$report = "C:\PS_Script\" + "DiskSpaceReport_" + "$Currdate.html"

#Run command to get free disk space from multiple servers and export output to HTML file
Get-WmiObject Win32_LogicalDisk -filter "DriveType=3" -computer (Get-Content C:\PS_Script\ServerNames.txt) | Select SystemName,DeviceID,VolumeName,@{Name="Size(GB)";Expression={"{0:N1}" -f($_.size/1gb)}},@{Name="FreeSpace(GB)";Expression={"{0:N1}" -f($_.freespace/1gb)}} | ConvertTo-HTMl | Out-File $report

When you run above PowerShell script, it will create a HTML file in C:\PS_Script folder.  Please make sure that you are running the PowerShell script using your admin account.

I hope you like this script.
