How to Fix Acrobat Not Opening PDFs on Mapped Network Drives
Question details
Adobe Acrobat fails to open PDF files located on a mapped network drive unless a local file is opened first.
- Product
- Adobe Acrobat
- Device & OS
- Windows 10
- Scenario
- Attempting to directly open a PDF file from a mapped network drive after opening an Outlook PDF attachment.
- Observed behavior
- Acrobat successfully opens Outlook attachments but will not open a PDF from a mapped network drive directly. A local file must be opened first to temporarily bypass the issue.
Ensure you have the exact folder path or drive letter for your mapped network drive handy before modifying security settings in Acrobat.
Add the Network Drive to Acrobat's Privileged Locations
Configure Enhanced Security settings in Adobe Acrobat to permanently trust the mapped network drive.
Adobe Acrobat uses an Enhanced Security mode to protect your computer from malicious documents. Because mapped network drives are treated as external or unsafe locations, Acrobat may restrict access to PDFs stored there. By adding the drive to your Privileged Locations, you can bypass this block.
Launch Adobe Acrobat, click on the 'Edit' menu at the top, and select 'Preferences' (or press Ctrl + K).
In the left-hand Categories pane, scroll down and click on 'Security (Enhanced)'.
Under the 'Privileged Locations' section, click on the 'Add Folder Path' button.
Browse to your mapped network drive or type in the exact folder path, select it, and click 'OK'.
Click 'OK' to save the Preferences, close Adobe Acrobat completely, and then try opening the network drive PDF again.
Open and Edit PDFs Seamlessly with WPS Office
Avoid complex security configuration errors by using WPS Office to effortlessly read, edit, and manage your PDF files from local and mapped network drives.
- 1. Download WPS Office: Download and install WPS Office for free from the official website.
- 2. Launch the PDF Tool: Open WPS Office and select the 'PDF' module from the main home screen.
- 3. Open Your File: Click 'Open', navigate directly to your mapped network drive, select your PDF file, and click 'Open' to view it immediately.
Frequently Asked Questions
Why does Acrobat block PDFs on my mapped network drive?
Acrobat's Enhanced Security feature treats files from network drives and the internet as potentially unsafe. This is a built-in sandbox measure designed to protect your computer from malicious scripts embedded in external documents.
Is it safe to add a network drive to Privileged Locations?
Yes, if the mapped network drive is managed by your organization's IT department or you are certain of the safety of the files stored there, adding it to Privileged Locations is perfectly safe.
Why does opening a local file first act as a workaround?
Opening a local file establishes a trusted active session in Acrobat, which sometimes temporarily overrides the rigid security blocks placed on subsequent file openings in that same session.
