Product: Adobe Acrobat Reader
Device & OS: Android
Scenario: Installing the app or opening a PDF document on an Android device.

Before you start

Before modifying application permissions, ensure your Android OS is updated so that your privacy and security settings reflect the most recent Android permission models.

Understand the Functional Purpose of All Files Access

Adobe Acrobat uses this permission strictly to locate, read, and save PDF files across your device's storage directories.

Modern Android versions restrict how apps access local storage to protect user privacy. Because PDFs can be downloaded via browsers, received in messaging apps, or transferred via USB, they are stored in various isolated folders.

To provide a seamless experience, Acrobat requests broad access to scan for PDFs, display recent files, and allow you to save edited documents back to their original locations without triggering constant permission prompts.

Finding scattered PDFs

The app uses the permission to scan your device's internal storage and SD card, aggregating all PDF files into a single, easy-to-navigate list within the Acrobat interface.

Saving modifications

When you highlight text, add comments, or fill out a form, the broad file access allows Acrobat to overwrite the existing file or save a new copy directly to your chosen local folder.

Understand the Functional Purpose of All Files Access

File Security Guarantee: Adobe explicitly states that the app does not automatically modify, move, or delete your local files without your explicit user action.

Solution 2

Manage or Restrict File Access Permissions

If you prefer not to grant broad access, you can manage or revoke the permission through Android settings, though it may limit some in-app features.

Frequently Asked Questions

Will Adobe Acrobat delete my files if I grant this permission?

No. Adobe's privacy policy and app mechanics ensure that Acrobat does not modify or delete your local files without your direct, explicit action.

Can I use Adobe Acrobat Reader without granting 'All files access'?

Yes, you can still open PDFs directly from your Android file manager or email app. However, in-app features like searching your entire device for documents or saving edits back to certain restricted folders will be unavailable.

How do I safely open a PDF without granting broad storage access?

You can use Android's built-in system PDF viewer, or use a file manager to locate the PDF and choose 'Open with...' to view the file in a sandbox mode without giving the reader app global storage permissions.
