Powershell folder size of folders without listing Subdirectories

Question

I have found several resources that use the following script to get folder sizes

$colItems = (Get-ChildItem $startFolder -recurse | Where-Object {$_.PSIsContainer -eq $True} | Sort-Object) foreach ($i in $colItems)     {         $subFolderItems = (Get-ChildItem $i.FullName | Measure-Object -property length -sum)         $i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB"     } 

The problem with that is it also lists the subdirectories ie:

c:\test\1 -- 10mb c:\test\1\folder -- 10mb c:\test\1\folder\deep -- 5mb c:\test\1\folder\tuna -- 5mb c:\test\2 -- 20bm c:\test\2\folder -- 20mb c:\test\2\folder\deep -- 10mb c:\test\2\folder\tuna -- 10mb 

I think you know see where I am going. What I am looking for is just the parent folder's results... SO:

c:\test\1 -- 10mb c:\test\2 -- 20mb 

How can this be accomplished with Powershell? ....

Answer 1

You need to get the total contents size of each directory recursively to output. Also, you need to specify that the contents you're grabbing to measure are not directories, or you risk errors (as directories do not have a Length parameter).

Here's your script modified for the output you're looking for:

$colItems = Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $true} | Sort-Object foreach ($i in $colItems) {     $subFolderItems = Get-ChildItem $i.FullName -recurse -force | Where-Object {$_.PSIsContainer -eq $false} | Measure-Object -property Length -sum | Select-Object Sum     $i.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB" }

This simple solution worked for me as well.

powershell -c "Get-ChildItem -Recurse 'directory_path' | Measure-Object -Property Length -Sum"
