How to Prevent Users from Overwriting a Master PDF on a Shared Drive
Question details
The user needs to protect a fillable master PDF on a shared network drive from being overwritten, while still allowing other users to open, fill it out, and save their own individual copies.

- Device & OS
- not provided
- Scenario
- Managing a fillable PDF form on a shared network folder accessed by multiple users who need to complete the form without altering the original template.
- Observed behavior
- Users need to be restricted to read-only access for the master file so they are forced to use the 'Save As' function to store their filled data in a separate location.
Ensure you have administrative or owner permissions for the shared drive folder so you can successfully modify the file properties and access rights.
Set the Master PDF to Read-Only via File Properties
The most effective method is to restrict file-level OS permissions so users can open the file but cannot save changes directly over the original document.
By changing the file attributes in your operating system, you prevent anyone (including yourself, until disabled) from accidentally saving over the master copy. When users try to save the filled form, the system will automatically prompt them to save a new copy elsewhere.
Open File Explorer (Windows) or Finder (Mac) and navigate to the shared drive folder where the master fillable PDF is stored.
Right-click the PDF file and select 'Properties' (on Windows) or 'Get Info' (on Mac) from the context menu.
Under the 'General' tab, check the box next to 'Read-only' at the bottom. Click 'Apply' and then 'OK' to save the changes.
Go to the 'Security' tab in the file properties, select the standard 'Users' group, click 'Edit', and ensure that 'Write' and 'Modify' permissions are unchecked for general users.
Apply PDF Password Protection for Editing
Use PDF editing software to set a permission password, restricting modifications to the document structure while explicitly allowing form filling.
Protect Your Master PDFs Easily with WPS Office
WPS Office provides robust PDF security features, allowing you to easily set passwords, restrict editing, and manage form-filling permissions to prevent users from overwriting your important master documents.
- 1. Open the Master PDF: Launch WPS Office and open your fillable PDF form.
- 2. Navigate to the Protect Tab: Click on the 'Protect' tab in the top ribbon menu and select 'Encrypt'.
- 3. Set Edit Permissions: Check the box for 'Set password to restrict editing and printing'. Enter a secure password.
- 4. Configure Allowed Actions: Under the allowed changes dropdown, choose 'Fill in form fields' and click Confirm.
- 5. Save the Document: Save the file to your shared drive. Users will now be able to fill it but must use 'Save As' to retain their data.
Frequently Asked Questions
Can users still fill out a read-only PDF?
Yes, users can open and type into the form fields of a read-only PDF. However, when they try to save their progress, the system will prompt them to use 'Save As' to create a new copy, protecting the original template.
What happens if a user ignores the 'Save As' prompt and tries to click Save?
If the file is set to read-only or lacks write permissions on the shared drive, the operating system will block the user from saving over the original file. It will typically display an error message or automatically force the 'Save As' dialog box to open.
Do I need special software to make a file read-only on a shared drive?
No special software is required. You can use the built-in file properties in your operating system (like Windows File Explorer or Mac Finder) to check the 'Read-only' or 'Locked' attribute.
How do I update or edit the master PDF later if it is set to read-only?
To update the master file, you will need to temporarily uncheck the 'Read-only' attribute in the file properties. Once disabled, you can open the file, make your structural changes, save it, and then reapply the 'Read-only' setting.
