Question details
Users are unable to locate their PDF files within the 'On This Device' storage section of the Acrobat Reader Mobile application.

- Product
- Acrobat Reader Mobile
- Device & OS
- not provided
- 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.
Check your mobile device's default File Manager app to verify that the PDF document hasn't been accidentally deleted from your internal storage or SD card.
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.
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.
Exit the PDF app and open the native 'Files' or 'My Files' application built into your mobile device.
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.
Tap on the located PDF document and select Acrobat Reader from the 'Open with' menu to successfully re-establish its location.

Easily Locate and Read Mobile PDFs with WPS Office
If your current PDF reader struggles to keep track of local files, WPS Office provides a smart built-in document scanner that automatically detects, organizes, and opens all PDF files on your device without losing track of them.
- 1. Install WPS Office: Download and install the WPS Office app from your device's app store.
- 2. Grant storage permissions: Open WPS Office and allow the app to access your device's local storage files.
- 3. Scan for documents: Navigate to the 'PDF' tab or use the file manager feature; WPS Office will automatically list all PDFs found on your device.
- 4. Open and edit: Tap any detected PDF to open it instantly for reading, signing, or annotating.

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.
