Streamlining OneDrive File Management with PowerShell

Effectively managing files in OneDrive is essential for ensuring collaboration and security within an organization. This PowerShell script automates the process of retrieving and managing files in a OneDrive account, making it easier for administrators to assess file status and permissions.
This script will:
1. Connect to OneDrive using Microsoft Graph.
2. Retrieve a list of files and their current permissions in a specified OneDrive directory.
3. Provide options for displaying or updating file permissions.
By using this script, IT administrators can enhance their ability to monitor and manage files in OneDrive efficiently.

# Install Microsoft Graph PowerShell module if not already installed
if (-Not (Get-Module -ListAvailable -Name Microsoft.Graph)) {
    Install-Module -Name Microsoft.Graph -Scope CurrentUser -AllowClobber
}
# Connect to Microsoft Graph
Connect-MgGraph -Scopes 'Files.Read.All', 'Sites.Read.All'
# Define the OneDrive site and folder path
$siteId = "your-site-id"  # Replace with your SharePoint site ID
$driveId = "your-drive-id"  # Replace with your OneDrive drive ID
# Retrieve all files in the specified OneDrive directory
$files = Get-MgDriveItem -DriveId $driveId -ItemId "root/children" 
Write-Host "=== Files in OneDrive ==="
foreach ($file in $files) {
    Write-Host "File Name: $($file.Name) - ID: $($file.Id) - Size: $($file.Size) bytes"
    $permissions = Get-MgDriveItemPermission -DriveId $driveId -ItemId $file.Id
    Write-Host "Permissions: "
    foreach ($perm in $permissions) {
        Write-Host "  Role: $($perm.Roles) - Granted To: $($perm.GrantedTo.User.DisplayName)"
    }
}
# Disconnect from Microsoft Graph
Disconnect-MgGraph
Write-Host "File management process completed."
