How to Limit the Number of OneDrive Uploads and Downloads
Question details
The user wants to restrict the number of files OneDrive uploads or downloads concurrently to prevent overwhelming a slow internet connection.
- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Syncing multiple files over a slow internet connection where concurrent transfers cause network congestion.
- Observed behavior
- OneDrive automatically uploads and downloads multiple files simultaneously, causing the internet connection to become overwhelmed and sluggish.
Check your current network speed and ensure that you have the latest version of the OneDrive sync client installed on your device.
Limit OneDrive Network Bandwidth Usage
Since OneDrive does not currently allow users to specify the exact number of concurrent file transfers, restricting the overall bandwidth limit is the best workaround to prevent slow internet connections from being overwhelmed.
The OneDrive sync client currently lacks a Group Policy setting or registry key to control the exact number of concurrent file transfers. However, you can manage the impact of simultaneous uploads and downloads by capping the network rate. This ensures OneDrive leaves enough bandwidth for your other applications.
Click the OneDrive cloud icon in the Windows taskbar notification area, click the gear icon (Help & Settings), and select 'Settings'.
In the Settings window, click on 'Sync and backup' in the left sidebar, then scroll down and expand 'Advanced settings'.
Under the 'Limit network speed' section, toggle the switches for Download rate and Upload rate, and enter a specific limit (e.g., 50 or 100 KB/s) that matches your network capabilities.

Frequently Asked Questions
Can I prioritize which files OneDrive uploads first?
Currently, the OneDrive sync client does not support manual file prioritization. It generally syncs files based on an internal algorithm prioritizing small files and the order in which they were modified.
Will limiting the upload speed in OneDrive fix my slow internet?
Yes. While it doesn't limit the number of files uploading at once, restricting OneDrive's network bandwidth in the settings prevents it from consuming your entire connection, leaving available bandwidth for web browsing and other applications.
Can I use third-party tools to restrict concurrent OneDrive uploads?
Third-party network management tools like NetLimiter can restrict the total bandwidth used by the OneDrive application, but they cannot alter OneDrive's internal logic to change the exact number of concurrent file transfers.
