Recursively count files in subfolders

Question

I am trying to count the files in all subfolders in a directory and display them in a list.

For instance the following dirtree:

TEST
    /VOL01
              


        

Answer 1

Something like this should work:

dir -recurse |  ?{ $_.PSIsContainer } | %{ Write-Host $_.FullName (dir $_.FullName | Measure-Object).Count }

• dir -recurse lists all files under current directory and pipes (|) the result to
• ?{ $_.PSIsContainer } which filters directories only then pipes again the resulting list to
• %{ Write-Host $_.FullName (dir $_.FullName | Measure-Object).Count } which is a foreach loop that, for each member of the list ($_) displays the full name and the result of the following expression

• (dir $_.FullName | Measure-Object).Count which provides a list of files under the $_.FullName path and counts members through Measure-Object

• ?{ ... } is an alias for Where-Object

• %{ ... } is an alias for foreach
