Question details
The user wants to access and open desktop and thumbnail files directly in Microsoft 365 Home without relying on dragging and dropping them from File Explorer.

- Product
- Microsoft 365 Home
- Device & OS
- not provided
- Scenario
- Trying to open local desktop files directly within the Microsoft 365 Home app or web interface.
- Observed behavior
- Files cannot be accessed directly through the interface; the user has to manually drag and drop files from the File Explorer into Microsoft 365 to open them.
Ensure that your Microsoft 365 application is fully updated and check whether your local Desktop folder is currently configured to sync with OneDrive.
Check OneDrive Desktop Sync Settings
If your Desktop folder isn't syncing properly with OneDrive, Microsoft 365 may struggle to locate your files natively in its main dashboard.
Microsoft 365 relies heavily on OneDrive for seamless file access. Enabling folder backup ensures your desktop files appear automatically in your Microsoft 365 recent files list.
Click the OneDrive cloud icon in your Windows system tray, click the gear icon (Help & Settings), and select 'Settings'.
Navigate to the 'Sync and backup' tab in the left menu and click on the 'Manage backup' button.
Ensure the toggle next to 'Desktop' is turned on, then click 'Save changes'. Your desktop files will now sync and be visible in Microsoft 365.

Use the Built-in Browse Menu
Instead of dragging and dropping from File Explorer, you can manually browse local file directories through the built-in Microsoft 365 Open menu.
Verify File Formats and Check for Errors
Sometimes specific thumbnail files or unsupported formats cannot be opened directly, requiring you to investigate file extensions or error messages.
Access Local Files Effortlessly with WPS Office
If Microsoft 365's cloud-dependent interface makes it difficult to manage and open local desktop files, consider switching to WPS Office. It provides a robust, traditional desktop experience that reads your local files natively without forcing cloud synchronization.
- 1. Download and Install: Download WPS Office from the official website and complete the quick installation process.
- 2. Open Local Files: Launch WPS Office and click 'Open' on the homepage to browse your local Desktop files immediately.
- 3. Edit Seamlessly: Open and edit your Microsoft-formatted files securely on your local drive without any syncing delays.

Frequently Asked Questions
Why do I have to drag and drop files into Microsoft 365?
The main Microsoft 365 dashboard prioritizes files stored in OneDrive. If your local Desktop is not synced to your OneDrive account, the dashboard won't display those files automatically, requiring you to manually drag them in or use the Browse dialog.
How do I stop OneDrive from interfering with my local desktop files?
You can unlink your desktop folder by opening OneDrive settings, clicking 'Manage backup' under the 'Sync and backup' tab, and turning off the toggle for the Desktop folder. Note that this means Microsoft 365 Web will no longer see these files automatically.
Can I open thumbnail preview files directly in Microsoft 365?
System thumbnail cache files (such as thumbcache.db) are used by Windows to display icons and cannot be opened as documents in Microsoft 365. Make sure you are trying to open the actual document file (like a .docx or .xlsx) rather than a system shortcut or image cache file.
