Fix OneDrive Uploads Stuck at 127 KB on Mac and Windows
Question details
Users are experiencing synchronization delays where file uploads intermittently pause at exactly 127 KB before taking several minutes to complete.
- Product
- OneDrive
- Device & OS
- macOS and Windows 10
- Scenario
- Uploading and synchronizing files, including very small files (5 MB or less), across different operating systems and network environments.
- Observed behavior
- The synchronization process abruptly stops at 127 KB. After pausing for 10 to 20 minutes, the upload finally completes. Recreating the folder temporarily restores syncing, but this is not scalable for extensive production folders.
Ensure your computer has a stable internet connection and verify that you have not exceeded your overall OneDrive storage limit before altering your folder structure or resetting the application.
Reset the OneDrive Synchronization App
Resetting the OneDrive client resolves corrupted synchronization states that cause file uploads to stall at specific sizes like 127 KB.
A corrupted folder synchronization state is often the root cause when uploads pause at exact byte counts across different devices. Resetting the OneDrive application clears these underlying state errors and forces the app to resync with the cloud.
Press the Windows key + R to open the Run dialog. Enter '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' and press OK. If you see a 'Windows cannot find' error, try '%programfiles(x86)%\Microsoft OneDrive\onedrive.exe /reset' instead.
Quit OneDrive. Open the Applications folder, right-click the OneDrive app, and select 'Show Package Contents'. Navigate to Contents > Resources and double-click the 'ResetOneDriveApp.command' or 'ResetOneDriveAppStandalone.command' file.
Once the reset command has finished executing, open OneDrive from your Start menu (Windows) or Applications folder (Mac) and sign back in if prompted to resume synchronization.
Recreate the Corrupted Folder
If resetting the application does not work, replacing the corrupted folder with a fresh one can temporarily force files to upload.
Experience Seamless Syncing with WPS Office
If Microsoft OneDrive continues to stall your workflow with sync errors, consider switching to WPS Office. It provides a robust, free Office suite with integrated WPS Cloud storage, ensuring smooth file synchronization and zero hassle.
- 1. Install WPS Office: Download the free WPS Office suite from the official website and install it on your PC or Mac.
- 2. Activate WPS Cloud: Open the application, click on your user profile in the top right corner, and sign in to activate your integrated cloud storage.
- 3. Save and Sync Seamlessly: Create or edit your documents and utilize the 'Save to Cloud' feature for instant, real-time synchronization across all your devices.
Frequently Asked Questions
Why does my OneDrive upload stop at exactly 127 KB?
This highly specific pausing issue often indicates a corrupted folder synchronization state or a bug in how the OneDrive client chunks file data for uploading. It is known to happen intermittently across both macOS and Windows operating systems.
Will resetting OneDrive delete my locally saved files?
No. Resetting the OneDrive app strictly clears the application's sync cache and resets connection settings. Your actual files, both locally stored on your hard drive and saved in the cloud, will remain untouched.
What information should I provide to Microsoft Support if the 127 KB bug persists?
If resetting the app and recreating folders do not resolve the issue, you should gather your exact OneDrive version, operating system details (e.g., Windows 10 or macOS version), account type, and the specific file or folder paths that are failing to sync.
Could network issues be causing the 127 KB sync pause?
While general network instability can cause upload delays, stopping consistently at 127 KB across entirely different environments (like a MacBook and a Windows 10 PC on separate networks) strongly suggests an application-level folder corruption rather than a basic network problem.
