Learn about Windows PowerShell
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
Didn't know about the -NoElement switch and it just happens that my last git commit can use this, thanks! Kudos :)
