Question details

Users are experiencing an issue where the Microsoft Word app on Android appends URL-encoded characters, such as %20 or %25, to file names when opening or saving documents stored in Dropbox.

How to Fix Incorrect Percent Signs in Word for Android File Names

Product: Microsoft Word for Android, Dropbox
Device & OS: Android
Scenario: Opening, editing, or saving cloud-hosted Word documents directly from the Dropbox integration within the Word for Android application.
Observed behavior: File names display with unexpected URL-encoded characters (like %20 instead of spaces) in the Word app, and there are occasional synchronization delays between Word and Dropbox on Android.

Before you start

Ensure your device has a stable internet connection for syncing, and check if the affected documents have special characters or spaces in their original file names.

Solution 1Recommended

Update Apps and Re-link Dropbox Account

Resolves integration glitches between Microsoft Word and Dropbox by ensuring both apps are fully updated and refreshing the cloud connection.

Because this behavior is limited to the Word and Dropbox Android integration, refreshing the connection bridge can often clear temporary URL-encoding bugs.

Update applications

Open the Google Play Store on your Android device, search for both Microsoft Word and Dropbox, and tap 'Update' if a newer version is available.

Remove Dropbox from Word

Open the Microsoft Word app, navigate to the 'Open' tab, tap on 'Manage storage accounts', and select the option to remove or unlink your Dropbox account.

Reconnect the account

Restart the Microsoft Word app, return to the 'Open' tab, tap 'Add a place', choose Dropbox, and sign back into your account to establish a fresh connection.

Reporting the Issue: If the problem persists after updating and re-linking, it may be a known software bug. Consider reporting it to Microsoft and Dropbox support with your specific Android and app version numbers.

Solution 2

Edit a Local Copy of the Document

Bypasses the cloud integration bug entirely by downloading the file to your Android device's local storage before editing.

Frequently Asked Questions

Why do %20 and %25 appear in my file names on Word for Android?

These are standard URL-encoded characters. The %20 represents a blank space, and %25 represents a percent sign. This occurs due to an integration glitch where the Word for Android app reads the Dropbox file path as a web URL instead of a standard file name.

Does this filename encoding issue affect the original Dropbox file?

No, the original file hosted on Dropbox usually retains its correct name. The encoded percent signs typically only appear locally within the Microsoft Word app's interface or when creating a new save directly from the Word app.

Will clearing the app cache permanently fix the percent sign issue?

Clearing the cache or reinstalling the apps might temporarily resolve synchronization delays, but if it is an active bug in the Word-Dropbox integration, the %20 characters may return until an official patch is released by the developers.

Can I manually rename the file inside Word to remove the %20 characters?

You can try using the 'Save As' feature in Word to rename the document and manually delete the %20 characters. However, it is often more reliable to rename or manage the file directly within the Dropbox app to prevent synchronization errors.
