Powershell - List subdirectories and count files per subdirectory - file

Question

I have a directory full of subdirectories that have any number of 0 to 300 files in them.
I want to output the subdirectory name and the number of files in that subdirectory
What I have so far is giving me 0 no matter how many actual files are in the subdirectory.
$dir = "C:\Folder\"
$subFiles = (Get-ChildItem $dir -recurse | where-object {$_.PSIsContainer -eq $true })
$subFiles | % {
Get-ChildItem -Path $_ -Force -Recurse | Measure-Object | Select-Object -ExpandProperty Count
write-host "$_"
}
Its also sometimes including the directories in which the script is being run ie "C:\Users\Blah\documents and settings\startmen" and causing errors.
Any help greatly appreciated thank you

Answer 1

You are using at least PowerShell 3.0 since you are using the -File parameter of Get-ChildItem so you dont need to use the where-object {$_.PSIsContainer -eq $true }. That has been replaced with the -Directory parameter. Loop through all the folders and collect the folder name and count of its files. I removed the -Recurse of the file count since that could be misleading. Put it back if it suits you better. The final Select-Object is to ensure the order of the output which is an object now that you could sort or do whatever you wanted with.
$dir = "C:\File"
Get-ChildItem $dir -Recurse -Directory | ForEach-Object{
[pscustomobject]#{
Folder = $_.FullName
Count = #(Get-ChildItem -Path $_.Fullname -File).Count
}
} | Select-Object Folder,Count
Insight
You were getting those errors before since you were not calling the full path in Get-ChildItem you were just calling the folder name. In the absence of a full path Get-ChildItem assumes you are looking for a folder in the current directory. That which is typically your user directory.

Answer 2

This method for count seems to be faster for remote directories.
$count = [System.IO.Directory]::GetFiles($_.Fullname).Count

Answer 3

This did exactly what I wanted :) Its not very pretty, but it worked..
$dir = "C:\folder\"
$subFiles = (Get-ChildItem $dir -recurse | where-object {$_.PSIsContainer -eq $true })
$subFiles | % {
$path = $dir+$_
$files = Get-ChildItem -Path $path -Force -Recurse -File -ErrorAction SilentlyContinue
write-host "$_ Files:" $files.count
}
