Introduction

Using PnP Powershell you can programmatically count files in a folder or the entire library in SharePoint Online that have unique permissions.

Count files with unique permissions in a folder

The following PnP cmdlets count files with unique permissions in a folder.

# Define the folder URL relative to the document library
$folderUrl = "/sites/yoursite/Shared Documents/YourFolder"
$list = "Shared Documents"

# Initialize the count for items with unique permissions
$fileCountWithUniquePermissions = 0;

# Get the folder
$folder = Get-PnPFolder -Url $folderUrl -Includes Files, Folders

foreach ($file in $folder.Files) {
    $fileItem = Get-PnPListItem -List $list -Id $file.ListItemAllFields.Id
    if ($fileItem.HasUniqueRoleAssignments) {
        $fileCountWithUniquePermissions++
    }
}


# Output the total count
Write-Host "Total files:  $fileCountWithUniquePermissions"

Count files or items with unique permissions in a list

The following lines can help you count files in a document library with unique permissions or items with unique permissions in a list.

# Define the list name
$listName = "YourListName"  

# Get all list items
$items = Get-PnPListItem -List $listName -PageSize 5000

# Initialize the count for items with unique permissions
$uniquePermissionCount = 0

# Iterate through each item to check for unique permissions
foreach ($item in $items) {
    # Check if the item has unique permissions
    if ($item.HasUniqueRoleAssignments) {
        # Increment the count if unique permissions are found
        $uniquePermissionCount++
    }
}

# Output the total count of items with unique permissions
Write-Host "Total items with unique permissions: $uniquePermissionCount"
