- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Navigating and identifying sensitive files and images stored securely inside the OneDrive Personal Vault.
- Observed behavior
- File thumbnails are completely hidden, making it difficult for the user to quickly identify images and documents without opening them individually.
Ensure your OneDrive Personal Vault is properly unlocked and authenticated on your device before attempting to organize or view your protected files.
Use List View and Descriptive Filenames
Since thumbnail previews are intentionally disabled for security, adjusting your folder view settings and naming conventions is the best workaround to identify files.
Microsoft intentionally hides file thumbnails and previews inside the OneDrive Personal Vault as a strict security measure. This prevents sensitive images and documents from being cached or viewed without fully opening the protected vault.
Currently, there is no setting to turn this security feature off. To easily identify your secure files, it is recommended to optimize how you name and view them.
Open Microsoft OneDrive, navigate to your Personal Vault, and authenticate your identity using two-factor authentication to access your files.
Click the 'View' tab at the top of your File Explorer or OneDrive web interface, and select 'List' or 'Details' to easily read full file names and modification dates.
Right-click on your files and select 'Rename'. Give each file a highly descriptive and specific name so you can easily identify its contents without needing a visual preview.

Secure and Edit Your Documents with WPS Office

- 2. Open Your Documents: Launch WPS Office and open your existing Microsoft Word, Excel, or PowerPoint files without losing any formatting.
- 3. Apply Document Encryption: Navigate to the 'Menu' tab, select 'Document Encryption', and set a secure password to protect your sensitive files.
