How to download all the files from OneDrive?

OneDrive is a cloud-based storage solution from Microsoft that lets you store files online and share them with others. You can access your OneDrive files from any device, and there are several ways to download all the files from your account (or anyone else’s account when you have access!). In this article, we’ll show you how to quickly download OneDrive for Business files through the web browser interface. We’ll also show you how to use PowerShell to download all of your OneDrive for Business files. So let’s get started!

Here are the options available to download OneDrive for Business site:

1. Select all files and folders and hit Download button in the toolbar
2. Use the sync option and select “Always Keep on this device”
3. Use the PowerShell script to download all files and Folders from OneDrive

Option 1: Download All Files and Folders from OneDrive for Business using Web Browser

Microsoft’s OneDrive for Business is a great way to store and share files. But what if you need to download all of the files from your OneDrive for Business account? Well, let me show you how to download all the files from your OneDrive for Business account.

Here is how to download all files from OneDrive for Business in just a few clicks:

1. Login to your OneDrive site. URL shortcut: https://YourDomain-My.sharepoint.com/ (or any other user’s OneDrive site – provided you have access to their OneDrive site already! If not, use How to Get Access to OneDrive for Business site of Other users?)
2. Select all files and folders and hit “Download” button from the toolbar.

This will download everything from the OneDrive site to a Zip file on your local PC.

Option 2: Download all files from OneDrive for business site using Sync Option

Let me show you how to download all your files from OneDrive so that you have a local copy on your computer with the Sync option. This way, you’ll always be able to access your files, even if there is an issue with OneDrive or the internet connection.

1. Browse to the OneDrive site which you would like to download files from.
2. Click on “Sync” button in the toolbar (Make sure you have OneDrive client installed in your local machine). This will start the sync process from OneDrive to your local disk.
3. Open the File Explorer, Locate the Folder created from the sync operation under “YourDomain” node, Right-click on the folder and choose “Always keep on this device”. This starts downloading everything from the OneDrive instead of just establishing the sync link.

        #Ensure All Folders in the Local Path
        $LocalFolder = $DownloadPath + ($_.FieldValues.FileRef.Substring($Web.ServerRelativeUrl.Length)) -replace "/","\"
        #Create Local Folder, if it doesn't exist
        If (!(Test-Path -Path $LocalFolder)) {
                New-Item -ItemType Directory -Path $LocalFolder | Out-Null
        }
        Write-host -f Yellow "Ensured Folder '$LocalFolder'"
    }
 
    #Get all Files from the folder
    $FilesColl =  $ListItems | Where {$_.FileSystemObjectType -eq "File"}
 
    #Iterate through each file and download
    $FilesColl | ForEach-Object {
        $FileDownloadPath = ($DownloadPath + ($_.FieldValues.FileRef.Substring($Web.ServerRelativeUrl.Length)) -replace "/","\").Replace($_.FieldValues.FileLeafRef,'')
        Get-PnPFile -ServerRelativeUrl $_.FieldValues.FileRef -Path $FileDownloadPath -FileName $_.FieldValues.FileLeafRef -AsFile -force
        Write-host -f Green "Downloaded File from '$($_.FieldValues.FileRef)'"
