We recently published an article about how to use PowerShell to find folders that contain a certain file type, such as the MP3 file format. I showed you how to search the file system using the DIR command. Although this command works fine when run locally, it might not perform very well if you want to search an entire drive. If you want to search remote computers, then querying the file system and even using PowerShell remoting with Invoke-Command is less than optimal. If you are targeting a specific root folder, it might not be that bad, but using Get-ChildItem (DIR) doesn’t scale very well, in my opinion. As an alternative, you can use Windows Management Instrumentation (WMI).
