How to Stop Security Warnings for Linked Local PDF Files
Question details
The user wants to prevent security warnings from appearing when opening PDF files that are hyperlinked within a main PDF document located in the same local folder.
- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Clicking a hyperlink inside a PDF menu or document to open another PDF file stored in the same local directory.
- Observed behavior
- The PDF reader triggers a security warning pop-up alert before allowing the locally linked PDF file to open.
Before modifying your security preferences, ensure that you completely trust the folder and the PDF files you are opening, as bypassing security warnings can expose your device to potentially malicious documents.
Add the Local Folder to Privileged Locations
The most secure and effective method to stop these warnings is to add the specific folder containing your linked PDFs to Acrobat's trusted directories.
By adding a folder to Privileged Locations, you tell Adobe Acrobat that any files executed or opened from this specific directory are safe, effectively stopping the security pop-ups without compromising the security of your entire system.
Launch Adobe Acrobat Reader. Navigate to 'Edit' > 'Preferences' on Windows, or 'Acrobat Reader' > 'Preferences' if you are using a Mac.
From the left-hand Categories menu, scroll down and select 'Security (Enhanced)'.
Look for the 'Privileged Locations' section at the bottom of the window and click on the 'Add Folder Path' button.
Browse your local directories, select the specific folder that contains both your main PDF and the linked PDF files, and click 'OK' to save your settings.
Modify PDF Trust Manager Settings
If adjusting privileged locations doesn't resolve the issue, you can modify the Trust Manager internet access settings to prevent broader restriction warnings.

Frequently Asked Questions
Why does Acrobat Reader display security warnings for safe local files?
Acrobat Reader uses an Enhanced Security feature designed to prevent malicious scripts from accessing your local file system. Because of this strict policy, it automatically flags any attempt to open secondary files via a hyperlink, even if the files are safe and stored locally.
Can I completely disable the Enhanced Security feature?
Yes, you can disable it by unchecking 'Enable Enhanced Security' in the Preferences > Security (Enhanced) menu. However, this is highly discouraged by security experts because it leaves your computer vulnerable to potentially harmful PDF files downloaded from the internet.
Will adding a folder to Privileged Locations affect the security of my other PDF files?
No. When you specify a folder in Privileged Locations, Acrobat Reader bypasses the strict security restrictions only for the PDFs located within that exact folder. All other PDFs on your computer will still be subjected to standard security checks.
