How to Find OneDrive Offline Files on Android for Obsidian
Question details
The user is trying to use a OneDrive folder as an Obsidian vault on Android but cannot find the local file path for the offline files.

- Product
- OneDrive
- Device & OS
- Android
- Scenario
- Attempting to select a OneDrive offline folder as a local vault in the Android Obsidian app.
- Observed behavior
- OneDrive does not expose a usable local file path for offline files in standard Android file managers, preventing Obsidian from accessing the vault directly.
Ensure you have the OneDrive application installed and logged in on your Android device, and download a reliable third-party synchronization application like OneSync from the Google Play Store.
Synchronize OneDrive to a Local Folder using OneSync
Since OneDrive hides offline files from standard file managers, the best workaround is to use a third-party app to automatically sync your OneDrive folder to an accessible local Android folder.
Microsoft designed the OneDrive app for Android to manage offline files internally, which means these files do not appear as normal local folders. Applications that require direct local folder access, such as Obsidian, cannot see them.
To bridge this gap, you can use a synchronization tool like OneSync. This tool downloads and keeps a standard local folder in sync with your cloud folder, providing Obsidian with the accessible path it requires.
On your Windows PC, locate the Obsidian vault folder inside your OneDrive directory, right-click it, and select 'Always keep on this device' to ensure files are fully downloaded.
Open your standard Android File Manager and create a new, empty folder in your internal storage to act as your local Obsidian vault.
Install and open OneSync. Connect your Microsoft account, then create a new sync pair. Choose your OneDrive vault folder as the remote source and the newly created local folder as the destination.
In OneSync, go to Settings > Synchronization. Enable 'Autosync' and set the schedule to a frequent interval (e.g., every 5 minutes). Ensure 'Instant upload' is enabled and allow syncing over both Wi-Fi and mobile data if preferred.
Launch the Obsidian app on your Android device, tap 'Open folder as vault', and select the local folder you created and synchronized in the previous steps.

Frequently Asked Questions
Where are OneDrive offline files stored on Android?
OneDrive stores offline files in a hidden system directory that is protected by the Android operating system. They can only be accessed internally by the OneDrive app and are not visible to standard file managers or third-party apps like Obsidian.
Can Obsidian sync directly with OneDrive on Android?
No, Obsidian requires an accessible local folder path to open a vault. Because the official OneDrive app does not expose its offline folders to the Android file system, direct syncing is not natively supported. You must use a third-party app like OneSync to bridge the gap.
Are third-party sync apps like OneSync safe for my files?
Yes, reputable sync applications like OneSync use the official Microsoft Graph API (OAuth) to access your OneDrive. This means they securely request permission to read and write your files without ever seeing or storing your Microsoft account password.
