How to Fix File URIs Not Opening Correctly in Microsoft To Do
Question details
The user is unable to open file URIs directly from Microsoft To Do tasks into File Explorer or other associated applications.

- Product
- Microsoft To Do
- Device & OS
- Windows, Android
- Scenario
- Attempting to click and execute a local or network file URI scheme saved within a Microsoft To Do task.
- Observed behavior
- The application fails to handle the file URI properly, resulting in malformed Edge URLs, unresponsiveness in Windows File Explorer, or application crashes on Android devices.
Ensure that the file or network path you are linking to actually exists on your local machine and verify that you are running the latest version of Microsoft To Do.
Test and Verify the URI in Windows Run
Confirm that your URI is valid and properly formatted outside of Microsoft To Do to isolate the issue to the application itself.
Before concluding that Microsoft To Do has a bug, it is crucial to test the exact file path. If the Windows operating system can open it organically, the failure is isolated to Microsoft To Do's internal URI handling.
Open the task in Microsoft To Do, highlight the exact file URI string you are trying to use, right-click, and select 'Copy'.
Press the 'Windows key + R' simultaneously on your keyboard to launch the Run command window.
Paste the copied URI into the 'Open' field and press 'Enter'. If File Explorer successfully opens the destination, the URI is valid and the issue is restricted to Microsoft To Do.

Use Standard Text Paths and Report the Bug
Use plain text paths as a temporary workaround and submit a detailed bug report to Microsoft forums for a permanent resolution.

Frequently Asked Questions
Why does Microsoft To Do crash on my Android device when I tap a file URI?
This is likely caused by an unhandled exception or an unsupported intent bug within the Android version of the app when it attempts to parse specific URI schemes. Until Microsoft patches this, avoid tapping local file links within the mobile app.
Are 'file://' links fully supported in Microsoft To Do?
While you can type or paste them into a task's note section, Microsoft To Do has known product limitations in properly hyperlinking and executing 'file://' URIs to open local applications like File Explorer.
Where is the best place to report technical bugs for Microsoft To Do?
Detailed technical issues, especially those involving unsupported URI handling or application crashes, are best reported on Microsoft Q&A, Microsoft Learn forums, or via the in-app 'Help & Feedback' channel.
