Question details
Users are experiencing excessive memory consumption by the OneDrive client when synchronizing a large number of SharePoint document libraries.

- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Syncing more than 100 SharePoint document libraries simultaneously on a single device.
- Observed behavior
- The OneDrive client uses an unusually high amount of RAM, causing system slowdowns for specific users or devices.
Ensure your device is connected to a stable internet network and save any open documents currently syncing to SharePoint to prevent data loss during troubleshooting.
Analyze Sync Volume and Update the OneDrive Client
Compare the number of synchronized files and test for application conflicts while ensuring you are running the latest OneDrive client version.
High memory usage is often directly related to the volume of files being synced or conflicts with other background applications. Narrowing down the root cause involves comparing sync loads between affected and unaffected users.
Right-click the OneDrive or SharePoint folder in File Explorer and select 'Properties'. Note the total number of files and folders, and compare this volume against unaffected users in your organization.
Open the Task Manager and temporarily close other non-essential applications. Monitor OneDrive's RAM usage to determine if another program is interfering with the synchronization process.
Download and install the newest version of the OneDrive client from the official Microsoft website, as updates frequently include memory management improvements.

Enable Files On-Demand and Stop Unnecessary Syncs
Reduce local RAM overhead by enabling Files On-Demand and unlinking SharePoint libraries that are not frequently accessed.

Frequently Asked Questions
Does syncing too many SharePoint files always cause high RAM usage?
Yes, syncing a massive number of files across many libraries forces the OneDrive client to continuously monitor them for changes, which naturally requires significantly more system memory.
How can I access SharePoint files without using the OneDrive sync client?
You can access and edit your files directly through a web browser by logging into your SharePoint site. This method uses zero background RAM since no local syncing is required.
How do I check what version of OneDrive I am currently running?
Click on the OneDrive cloud icon in your system tray, click the gear icon to enter Settings, and navigate to the 'About' tab. Your current version number will be displayed at the top of the window.
