Question details
Users experience OneDrive file uploads stopping or failing before completion, particularly when attempting to upload large files through a web browser.

- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Uploading large files or directories to OneDrive via a web browser or client.
- Observed behavior
- The upload process freezes, interrupts, or stops partway through, failing to complete the file transfer successfully.
Ensure your internet connection is stable and that you have enough available storage space in your OneDrive account before attempting large file transfers.
Use the OneDrive Desktop Synchronization Client
For large files, the desktop sync client is much more reliable than browser-based uploads because it handles network interruptions gracefully and resumes automatically.
Web browsers are highly sensitive to brief network timeouts. If your connection drops even for a second, a large browser upload can fail. The native OneDrive sync client resolves this by managing the upload in the background.
Download and install the OneDrive desktop application if it is not already set up on your computer.
Launch OneDrive and sign in with your Microsoft account to link your local PC to your cloud storage.
Open File Explorer (Windows) or Finder (Mac) and navigate to the newly created OneDrive folder in your sidebar.
Move or copy your large files directly into this local OneDrive folder. The client will automatically sync them to the cloud in the background.

Verify File Size, Name, and Path Restrictions
OneDrive enforces specific limitations regarding file sizes, special characters in file names, and total path lengths that can cause active uploads to halt.
Enhance Your Document Workflow with WPS Office
If cloud syncing issues are disrupting your document management, consider switching to WPS Office. It provides a lightweight, seamless environment for creating and editing documents with robust built-in cloud storage options, familiar user interfaces, and flawless compatibility with all Microsoft Office formats.
- 1. Download the installer: Visit the official WPS Office website and click the free download button.
- 2. Install the software: Run the installer and follow the on-screen prompts to set up WPS Office on your device.
- 3. Open and sync documents: Launch WPS Office, open your existing Microsoft Office files, and easily save them to your preferred cloud storage.

Frequently Asked Questions
What is the maximum file size I can upload to OneDrive?
OneDrive currently supports uploading individual files up to 250 GB in size, provided you have sufficient storage space available in your Microsoft account.
Why does my browser upload fail while the desktop app succeeds?
Web browsers rely on continuous, uninterrupted sessions. If your network connection fluctuates or drops for even a moment, the browser terminates the upload. The desktop sync client is specifically engineered to pause and automatically resume transfers during network instability.
Can an unstable Wi-Fi connection cause OneDrive uploads to freeze?
Yes, fluctuating bandwidth or intermittent packet loss on a Wi-Fi network is a common cause of upload stalls. Switching to a stable, wired Ethernet connection often resolves this issue when handling large files.
Are there specific file types that OneDrive blocks from uploading?
While OneDrive allows the vast majority of file types, it may restrict or block certain temporary files (such as .tmp), system files, or files actively being used by another program on your computer.
