Fix OneDrive Folder Shows Empty on Android but Works on Mac
Question details
The user needs to resolve an issue where a specific OneDrive folder properly displays files on a Mac computer but appears completely empty when accessed from an Android phone.

- Product
- Microsoft OneDrive
- Device & OS
- Android 12 and macOS Ventura 13.6.1
- Scenario
- Accessing synced files across multiple devices (Mac and Android mobile application).
- Observed behavior
- The OneDrive application on Android displays an empty folder. Concurrently, the Mac OneDrive client reports multiple sync issues and is stuck in a synchronization loop.
Ensure both your Mac and Android devices have a stable internet connection, and verify that you have your correct Microsoft account credentials ready before troubleshooting.
Resolve Synchronization Errors on Mac
Fixing local sync errors on your Mac ensures that files actually reach the cloud, making them visible to your Android application.
If OneDrive on your Mac is experiencing synchronization issues, files will not upload to the cloud server, which means your Android phone cannot see them. Fixing naming conventions and path lengths on the Mac side is often the primary solution.
Click the OneDrive cloud icon in the Mac menu bar at the top of your screen. If there are errors, click on the warning indicating the number of sync issues to see the list of problematic files.
Check the flagged files for unsupported characters such as <, >, :, ", |, ?, *, /, or \. Rename the files locally on your Mac to remove these characters.
If a file name or folder path is too long (exceeding 400 characters), move the file closer to the main OneDrive root directory to shorten the path.
After renaming or moving the files, wait for the OneDrive client to finish uploading. The menu bar icon should eventually state that your files are 'Up to date'.

Verify Web Access and Re-login on Android
Confirming cloud availability via a web browser and refreshing the Android app connection resolves cache and account discrepancies.

Frequently Asked Questions
Why does OneDrive show a folder but no files inside on my phone?
This commonly occurs when the folder structure has synced to the cloud, but the actual files inside are still uploading from another device (like a Mac) or are stuck due to local synchronization errors.
What characters are invalid in OneDrive file names?
OneDrive does not support file names containing characters such as ", *, :, <, >, ?, /, \, or |. Removing these characters from your file names on your Mac will often resolve immediate sync blockages.
How can I clear the OneDrive cache on my Android phone?
Go to your Android device Settings, tap on Apps, locate OneDrive, select Storage, and tap 'Clear Cache'. This forces the app to pull fresh data from the cloud the next time you open it, which can fix display issues.
