How to Fix OneDrive SharePoint Sync Not Enough Free Space for Files Error

Introduction

When attempting to sync files between OneDrive and SharePoint, you may receive an "There's not enough space in your OneDrive for this file" error. This not only disrupts your workflow but also prevents you from saving new files to OneDrive.

Importantly, this error does not always indicate that your OneDrive account is full. In some cases, it can also occur even when you have ample cloud storage available. This guide covers practical methods to restore smooth syncing between OneDrive and SharePoint.

Why Does OneDrive Say "Not Enough Free Space for Files"?

The "not enough free space" error can be triggered by several different factors. Understanding the root cause can help you choose the most effective fix. Listed below are some leading causes:

Insufficient OneDrive storage quota: If your OneDrive account has reached its storage limit, new files cannot be uploaded or synchronized until space is freed up or additional storage is purchased.

Lack of local disk space: Even when plenty of cloud storage is available, OneDrive still requires free space on your computer to process and synchronize files. A nearly full system drive can cause sync operations to fail.

Large SharePoint libraries: When syncing a SharePoint document library containing a large number of files, OneDrive may struggle to process the data efficiently, resulting in storage-related sync errors.

Files On-Demand configuration issues: If Files On-Demand is disabled, OneDrive may attempt to download all files locally, quickly consuming available disk space and triggering the error.

Sync cache or client problems: Corrupted OneDrive cache files, outdated sync clients, or temporary synchronization glitches can sometimes generate incorrect free-space warnings.

Account or permission issues: In some cases, SharePoint storage quotas, restricted permissions, or account synchronization problems may prevent files from syncing even when sufficient storage appears to be available.

How to Fix OneDrive SharePoint Sync Not Enough Free Space for Files Error

The good news is that most of these issues can be resolved without deleting important files. In this section, we'll walk through several proven methods to fix the OneDrive SharePoint sync not enough free space for files error and restore normal synchronization.

Fix 1. Enable "Files On-Demand"

Files On-Demand is designed to reduce local storage usage by keeping files online until you need them. When this feature is disabled, OneDrive may attempt to download every file from a SharePoint library to your computer, quickly consuming disk space and triggering sync errors. Enabling it allows OneDrive to sync file placeholders instead of full copies, which is often enough to eliminate the "not enough free space" message.

Step 1. Click the OneDrive icon in the Windows taskbar and select "Settings".

Step 2. Switch to the "Sync and backup" tab and click "Advanced settings".

Step 3. Locate Files On-Demand and click "Free up disk space". The system automatically converts synced files to online-only status to instantly free up local disk space.

Step 4. Restart OneDrive and try again to sync the SharePoint library.

Fix 2. Check Local Drive Space

Even if your OneDrive account has plenty of available cloud storage, OneDrive still requires temporary local storage to process files during synchronization. If the drive containing your OneDrive folder is nearly full, syncing may fail. Checking and freeing local disk space is one of the quickest ways to resolve the error on your device.

★Tips:

When syncing large files or compressed archives, OneDrive first creates temporary data chunks locally in %LOCALAPPDATA%\Microsoft\OneDrive\settings or the cache folder. Even if you have 1TB of cloud storage available, the OneDrive not enough free spacce error will pop up immediately if the free space on drive C is smaller than the size of that single file.

Step 1. Open File Explorer and select "This PC".

Step 2. Check the available free space on the drive where OneDrive is installed.

Step 3. Delete unnecessary files, empty the Recycle Bin, or move large files to another drive.

Step 4. Restart OneDrive and attempt the sync again.

Fix 3. Check SharePoint Storage Quota

In some environments, the issue originates from SharePoint rather than OneDrive. A SharePoint site or document library may have reached its storage allocation limit, preventing additional files from syncing. Verifying the available SharePoint storage can help determine whether the problem is caused by organizational storage restrictions instead of your personal OneDrive quota.

Step 1. Sign in to the SharePoint admin center.

Step 2. Navigate to "Active sites" and select the affected site. Change the "Site storage limits" to "Manual" and save the changes.

Step 3. Then, select the affected site and click "Storage" at the top of menu, increase the "Maximum storage of this site" and save the change.

Fix 4. Clear Stuck Cache

A corrupted sync cache can cause OneDrive to display incorrect storage warnings even when sufficient space is available. Resetting the sync cache forces OneDrive to rebuild its local database and establish a fresh connection with SharePoint. This can resolve many unexplained sync issues without affecting files stored in the cloud.

Step 1. Press "Win" + "R" to open the Run dialog. Enter the following command and press "Enter":

%localappdata%\Microsoft\OneDrive\onedrive.exe /reset

Step 2. Wait for OneDrive to restart automatically.

Step 3. Sign in again if prompted and verify whether syncing resumes normally.

Fix 5. Choose Specific Folder to Sync

Syncing an entire SharePoint library may overwhelm devices with limited storage or resources. Instead of downloading everything, you can configure OneDrive to synchronize only the folders you actively use. This reduces storage consumption, improves sync performance, and minimizes the likelihood of encountering OneDrive "not enough free space" errors.

Step 1. Open OneDrive Settings, select "Account" and click "Choose folders".

Step 2. Uncheck folders that do not need to be synchronized locally.

Step 4. Save the changes and allow OneDrive to update the sync configuration.

Fix 6. Empty OneDrive Recycle Bin

Files stored in the OneDrive Recycle Bin continue to count toward your storage quota until they are permanently deleted. As a result, if your OneDrive storage is truly running low, emptying the Recycle Bin can immediately recover quota and resolve the OneDrive SharePoint sync not enough free space for files error.

Step 1. Sign in to OneDrive on the web, select "Recycle Bin" from the left navigation pane.

Step 2. Review the deleted files and confirm that none are needed.

Step 3. Click "Empty Recycle Bin" to permanently remove the files.

Fix 7. Upgrade Your OneDrive Storage Plan

If both local storage and SharePoint quotas are sufficient but your OneDrive storage is genuinely full, upgrading your plan may be the most practical solution. Additional storage eliminates quota limitations and provides room for future file growth, especially for users who regularly sync large SharePoint libraries.

Step 1. Sign in to your OneDrive account online and open Manage Storage from your account settings.

Step 2. Review the available Microsoft 365 and OneDrive storage plans.

Plan	Monthly	Yearly	Cloud Storage
Microsoft 365 Basic	$1.99	$19.99	100GB
Microsoft 365 Personal	$9.99	$99.99	1TB
Microsoft 365 Family	$50	$498	6TB

Step 3. Select a plan that meets your storage requirements and complete the upgrade process.
