PowerTip: Use PowerShell to Count Types of Photos

Summary: Use Windows PowerShell to count the different types of photo files on your computer.

 How can I use Windows PowerShell to figure out how many of each type of photo file I have on my computer?

 Use the Get-ChildItem cmdlet to retrieve specific types of photograph files, and then pipe the results to the 
          Group-Object cmdlet, group on the Extension property, and use the –NoElement switch to remove
           individual file information:

Get-ChildItem -Recurse -Include *.jpg, *.cr2, *.png, *.bmp -Path e:\ | Group-Object extension -NoElement
