Question details
Users experience missing files or empty folders when uploading large folder trees to OneDrive for Business via the web browser on macOS.

- Product
- OneDrive for Business
- Device & OS
- macOS
- Scenario
- Uploading large batches of files or complex folder structures to the cloud.
- Observed behavior
- The web interface creates the folder structure but fails to upload all the individual files, leaving empty folders online.
Ensure you have the latest OneDrive desktop sync client installed on your Mac and verify your internet connection is stable before attempting large batch uploads.
Use the Local OneDrive Sync Client for Uploads
The local desktop sync client handles large file batches and complex folder trees much more reliably than the browser-based web interface.
Web browsers can time out or drop connections during massive file transfers, leading to missing files inside uploaded folders. Switching to the native sync client ensures a persistent and stable connection for large uploads.
Cancel any ongoing folder uploads in the OneDrive web interface to prevent conflicts or duplicate files.
Open Finder, locate your local OneDrive folder, and drag the files or folders you want to upload into it. It is best to do this in smaller batches rather than all at once.
Watch the OneDrive status icons in the menu bar and next to the files in Finder to ensure the synchronization completes successfully.
If any individual files fail to sync, manually select them and drag them into the folder again to force a retry.

Enable Files On-Demand to Save Local Storage
After uploading large folders via the sync client, you can remove the local copies while keeping them accessible in the cloud.
Edit Your Synced OneDrive Documents Seamlessly with WPS Office
While you manage your OneDrive file uploads on your Mac, you can use WPS Office to effortlessly open, edit, and save your Word, Excel, and PowerPoint documents. It is a highly compatible, fast, and free alternative to Microsoft Office.
- 1. Install WPS Office: Download and install WPS Office for Mac from the official website.
- 2. Open OneDrive files: Launch WPS Office, click 'Open', and navigate to your local OneDrive sync folder in Finder to select your document.
- 3. Edit and save automatically: Make your edits in WPS Office. When you click Save, the OneDrive client will automatically sync the updated file back to the cloud.

Frequently Asked Questions
Why are my uploaded OneDrive folders empty on my Mac?
When uploading large folder trees via the web browser, the connection may time out or drop before all individual files are uploaded, leaving only the empty folder structure. Using the OneDrive desktop sync client resolves this issue.
What do the OneDrive status icons mean on macOS?
A cloud icon means the file is online-only and takes up no local space. A green check mark indicates the file is downloaded and available offline, while a syncing icon (circular arrows) means the file is currently uploading or downloading.
How can I upload thousands of files to OneDrive reliably?
Instead of uploading all files at once through a web browser, move them into your local OneDrive folder using Finder in smaller batches. Allow the desktop client to handle the synchronization in the background.
