Scenario
Attempting to access previously opened or stored local PDF files through the mobile app's directory.
Observed behavior
PDF files unexpectedly disappear from the 'On This Device' list, often after being cleared from the Recent list or modified externally, resulting in missing documents.

Solution 1Recommended

Locate and Reopen the File Manually

Use this method to manually find and re-link your PDF if the app has lost track of the file path due to relocation or modification.

When a file is moved, renamed, or modified outside of Acrobat Reader Mobile, the application may lose its access permissions or directory path to that file, causing it to vanish from the 'On This Device' tab.

1
Check for the location icon

Open Acrobat Reader Mobile and look for a location icon beneath the file name in your Recent list. If no icon appears, the app can no longer access the file's current location.

2
Open your device's file manager

Exit the PDF app and open the native 'Files' or 'My Files' application built into your mobile device.

3
Search for your PDF

Use the search bar at the top of the file manager to search for the specific document name, or type '.pdf' to view all stored PDF files.

4
Reopen the file

Tap on the located PDF document and select Acrobat Reader from the 'Open with' menu to successfully re-establish its location.

Locate and Reopen the File Manually
Storage Permissions: Ensure you have granted the app full permission to read local device storage in your mobile settings so it can discover your files.

Frequently Asked Questions

Why did my PDF suddenly disappear from the 'On This Device' list?

This issue typically occurs if the PDF was moved to a different folder, renamed using another app, deleted, or if your device's operating system reset app storage permissions.

Does clearing the Recent list delete my actual PDF files?

No. Clearing the Recent list in a PDF reader only removes the shortcut history. Your actual PDF files remain safely stored in your device's internal memory or SD card.

How can I prevent my files from missing in the app again?

Avoid moving or renaming PDF files through third-party file managers while they are actively tracked by your PDF app. Saving all your PDFs into a dedicated, stationary folder can also prevent this issue.
