Just a tip. This will help you to list files count by extension.

Get-Childitem c:\local -Recurse | where { -not $_.PSIsContainer } | group Extension -NoElement | sort count -desc

    If you’re using a newer version of PS, you can replace the where clause with -file.

    get-childitem c:\local -file |group Extension -NoElement |sort Count -desc

    Don’t know how much faster this is, but there is a performance improvement.

    How to do output in percent (or better both)?
    I don’t have a mind how to do it in one string with only one pass.

    E para verifica o tamanho ocupado no disco por cada extensão?

    • Wintel Rocks October 8, 2018, 8:30 pm

      No provision available to check the space occupied by each extension type.

    Man… in 2019 this is still gold. If you are using the latest PS version try the following if yours is not working:

    Get-ChildItem C:\windows\system32 -Recurse | Where { -not $_.PSIsContainter } | group Extension | Select Count, Name | Sort Count -Descending

    Cheers!

    That’s awesome! Just what I needed.

    I modified it a bit so it will prompt for the path (UNC paths work with this, which is what I need):

    $Path = Read-Host -Prompt ‘What is the directory or path?’
    Get-Childitem $Path -Recurse | where { -not $_.PSIsContainer } | group Extension -NoElement | sort count -desc

    is there a way to speed this up? My folders have in excess of 3-10M files each and this is taking forever.
    Help would be appreciated!!
