PowerShell Script to list all the files and folders that are being shared in a document library

Question

Hello,

I am trying to find out which folders or files on a Document Library are being shared, either internally or externally, and who was it shared to.

Is there a powershell script that does this?

Best.

Hi @Xia, Henry,

Try this PnP PowerShell script.

# Import the PnP PowerShell module
Import-Module PnP.PowerShell

# Variables
$siteUrl = "https://yourdomain.sharepoint.com/sites/yoursite" # Replace with your SharePoint site URL
$libraryName = "Documents" # Replace with the name of your document library
$adminUsername = "******@yourdomain.com" # Replace with your admin username
$adminPassword = "YourPassword" # Replace with your admin password

# Connect to SharePoint Online
Connect-PnPOnline -Url $siteUrl -Credentials (Get-Credential -UserName $adminUsername -Password (ConvertTo-SecureString $adminPassword -AsPlainText -Force))

# Function to list shared files and folders in a library
function Get-SharedItemsInLibrary {
    param (
        [string]$libraryName
    )

    # Get all items in the library
    $items = Get-PnPListItem -List $libraryName -PageSize 1000

    foreach ($item in $items) {
        $itemType = $item.FileSystemObjectType # File or Folder
        $itemUrl = $item.FieldValues.FileRef # Server-relative URL of the item

        # Check if the item is shared
        $sharingInfo = Get-PnPFileSharingInfo -Url $itemUrl

        if ($sharingInfo.SharingLinks -or $sharingInfo.SharedWithUsers) {
            Write-Host "Shared $($itemType): $($itemUrl)"

            # Check for sharing links
            if ($sharingInfo.SharingLinks) {
                Write-Host " Shared via links:"
                foreach ($link in $sharingInfo.SharingLinks) {
                    Write-Host " - Link: $($link.Url)"
                }
            }

            # Check for users the item is shared with
            if ($sharingInfo.SharedWithUsers) {
                Write-Host " Shared with users:"
                foreach ($user in $sharingInfo.SharedWithUsers) {
                    Write-Host " - User: $($user.UserPrincipalName)"
                }
            }
        }
    }
}

# Call the function to list shared items in the library
Get-SharedItemsInLibrary -libraryName $libraryName

# Disconnect from SharePoint Online
Disconnect-PnPOnline

Remember to replace parameters with your own and ensure you have admin permission to the SharePoint site.
