Issue in PowerShell with setting inheritance

Question

I have a script that I need some assistance in configuring permission inheritance on a collection of folders and subfolders
Here's what I have so far:
cls
Set-Location "C:\Set-ACL"
$log = "C:\Set-ACL\Folders.txt"
#Gets the ACL's from a folder with correct permissions set
$ACL = Get-Acl -Path "C:\Folder\subfolder\subfolder\subfolder"
$Folders = Get-ChildItem -Path "E:\Folder\Subfolder\*\*" | Select-String -pattern "01-"
$Folders >> $log
Start-Process $log -Wait
#Function to pause script while ignoring certain keys like Ctrl etc.
'Function Pause4user($M = "Press any key to continue setting ACL's Ctrl + C to quit . . . ") { If ($psISE) { $S = New-Object -ComObject "WScript.Shell"; $B = $S.Popup("Click OK to continue.", 0, "Script Paused", 0); Return }; Write-Host -NoNewline $M; $I = 16, 17, 18, 20, 91, 92, 93, 144, 145, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183; While ($K.VirtualKeyCode -Eq $Null -Or $I -Contains $K.VirtualKeyCode) { $K = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") }; Write-Host }'
Pause4user
foreach ($Folder in $Folders)
Set-ACL -Path $Folders -AclObject $ACL
Write-Host "ACL's Set"
Remove-Item $log
The issue i'm finding is that the permissions I have defined in the variable $ACL are not passed to all subfolders and using -recurse after the Get-ChildItem looks like it would do the job but doesnt work because of the 260 character limit in the path.
Is there a way to set the permissions on the folders returned in the $Folders variable and inherit these permissions to everything underneath it therefore not running into the path limit?
P.S. Go easy on the script it was put together quickly!
Thanks in advance

Hi Jack,
you can enforce childfolders accepting inheritance by getting their respective Acl, und using the
SetAccessRuleProtection method on the target folders.
If path length is escalating, you may want to consider doing one of these:
Temporarily create junctions to shorten the path.
Redesign your storage to be (or appear) more flat
I think there are other tools out there that can handle the path issue, but I don't have one at hand I can recommend - I have never had to design paths that long.
Cheers,
Fred
Ps.: Some shameless advertisement:
This function will create junctions for you, if you need something for that. You can remove them afterwards like any other shortcut.
