All PowerShell Versions
Here is some simple code that reads the NTFS permissions from one folder and applies the exact same settings to another. Note that both folders must exist:
$FolderToCopyFrom = 'C:\folder1' $FolderToCopyTo = 'C:\folder2' $securityDescriptor = Get-Acl -Path $FolderToCopyFrom Set-Acl -Path $FolderToCopyTo -AclObject $securityDescriptor
Cloning a security descriptor may require Administrator privileges. Note that all security rules on the second folder are overwritten by the security information taken from the first folder.
