  • In Windows 10 and later you need to be sure long path name is turned on. There is no other way except converting the name to its device equivalent but you can only do that if you already know the name.

  • hi Anrck, 

    I see you pb. You would like to do a tree-size in a script but you are facing problems with Acces denied and path too long, exact ?

    Have you tested the Try-catch-finally parameter in you script ? Im' thinking the solution is in this way.

    Just one link, but there are many others : Powershell-exceptions-everything-you-ever-wanted-to-know

    you have already identified the 2 types of problem you may be facing. For each error, you get a typical error message. This is these types you must catch and manage in try-catch

    $P = 'C:\Users\acherkao\Desktop\outiles'

    try {
    Get-ChildItem -force $P -Recurse | ? { ( $_.PSIsContainer ) } | 

    foreach {

    Get-ChildItem $_.FullName -Force -File | Select-Object  Name, @{Name=”Size”;Expression={ '{0:N2} MB' -f ($_.Length / 1MB)}}

    $size = 0
    Get-ChildItem -recurse -force $_.fullname -ErrorAction SilentlyContinue | foreach { $size += $_.length }

    $_.FullName, '{0:N2} MB' -f ($size / 1MB)


    Write-Host denied access to $_.FullName

    $files = Get-ChildItem $P -Force -Recurse |Where-Object { $_.Length -gt 20MB } | Select-Object Name,@{Name="size";Expression={ ' {0:N2} MB' -f ($_.Length / 1MB)}}
    Write-Host `n******* Taille des fichiers supérieur à 20MB ********
    Write-Host $files
    Write-Host `n******* LastModificationTime **********
    $lastmodifile = Get-ChildItem $P -Force -Recurse | sort LastWriteTime -Descending | select-object fullname,lastwritetime | select -first 1
    Write-Host $lastmodifile

    Write-Host `n***** liste des contenus des réps *********
