Managing folder permissions is crucial for maintaining security and proper access control in any shared environment. In this guide, we will walk through a simple yet effective method to export folder permissions from a specified directory and its subdirectories into a CSV file using PowerShell. This is particularly useful for administrators who need to audit or document access permissions across a shared network drive.
Prerequisites
Before you begin, ensure you have the following:
- Administrative access to the machine where the script will be run.
- PowerShell installed on your system (version 3.0 or higher is recommended).
Step-by-Step Instructions
- Open PowerShell as Administrator:
- Press
Win + X
and select “Windows PowerShell (Admin)” or search for PowerShell in the Start menu, right-click, and select “Run as administrator”.
- Run the PowerShell Script:
- Copy and paste the following script into the PowerShell window:
powershell Get-ChildItem "D:\Shared" -Recurse | Get-Acl | Select-Object Path, Owner, AccessToString | Export-Csv -Path "D:\share_folder_permission.csv" -NoTypeInformation
- Press
Enter
to execute the script.
Explanation of the Script
- Get-ChildItem “D:\Shared” -Recurse:
This command retrieves all items (folders and files) starting from the “D:\Shared” directory and includes all subdirectories. The-Recurse
parameter ensures that the search is recursive, meaning it will include all levels of the directory structure. - Get-Acl:
TheGet-Acl
cmdlet gets the security descriptor (ACL – Access Control List) of each item retrieved byGet-ChildItem
. This includes information about who has access to the item and what type of access they have. - Select-Object Path, Owner, AccessToString:
This part of the script selects specific properties to include in the output: the path of the item, the owner of the item, and the access permissions in a readable string format. - Export-Csv -Path “D:\share_folder_permission.csv” -NoTypeInformation:
Finally, theExport-Csv
cmdlet exports the selected properties to a CSV file at the specified path “D:\share_folder_permission.csv”. The-NoTypeInformation
parameter omits the type information from the CSV output, making it cleaner and more readable.
Result
Once the script has been executed, you will find a CSV file named “share_folder_permission.csv” in the root of the D: drive. This file contains a comprehensive list of all folders and their respective permissions within the “D:\Shared” directory and its subdirectories.
Benefits
- Documentation:
Having a documented list of folder permissions is invaluable for audits and compliance purposes. - Security:
Regularly exporting and reviewing permissions can help identify any unauthorized access or permission changes. - Management:
Simplifies the task of managing and adjusting permissions, as you have a clear overview of the current settings.
By following these steps, you can effectively export and review folder permissions, ensuring that your shared directories are secure and properly managed.
