Fix File Locking Issues for Shared PDF Editing in Adobe Acrobat
Question details
Users need a reliable way to prevent file conflicts when multiple users edit a PDF on network storage, as Acrobat lacks automatic file locking.

- Product
- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Multiple team members collaborating on a single PDF document stored on a shared network drive.
- Observed behavior
- Acrobat does not automatically lock the file while one user is editing it, creating a risk of team members overwriting each other's changes.
Ensure all collaborating team members have access to the shared network drive and that you have saved a backup copy of the original master PDF before testing new review workflows.
Set Up Acrobat Shared Reviewing
Use Acrobat's Shared Review feature to manage feedback centrally without overwriting the core document.
Shared Reviewing allows multiple users to add comments to a PDF simultaneously. The comments are stored on an internal server (like SharePoint or a network folder) rather than directly altering the original file.
Open the PDF in Acrobat, navigate to the 'Tools' menu, select 'Send for Review' or 'Share', and choose the Shared Review option.
Follow the setup wizard to specify your internal server, SharePoint workspace, or network folder where comments will be collected. You may need assistance from your IT administrator to ensure the correct folder permissions are applied.
Add the email addresses of the users who need to review the document and send the invitation directly through Acrobat.

Frequently Asked Questions
Why doesn't Acrobat automatically lock PDF files on a network drive?
Acrobat DC does not have a native check-in/check-out or file-locking mechanism for standard network drives. It relies on advanced document management systems (like Microsoft SharePoint) to handle file locking and version control.
What is an FDF file in Acrobat?
An FDF (Forms Data Format) file is a lightweight text file that exports only the comments, annotations, and form data from a PDF. This allows you to share feedback via email or a network folder without having to send the entire bulky PDF document.
Can multiple people edit a PDF at the exact same time in Acrobat?
Standard PDF text editing does not support real-time co-authoring. However, Acrobat's Shared Review feature does allow multiple users to add comments and annotations to the same document simultaneously.
