Question details

The user wants to stop OneDrive from generating duplicate copies of a PDF file (with a computer name appended) when multiple people edit the document at the same time.

How to Prevent Duplicate PDF Files in OneDrive When Multiple Users Edit

Product: OneDrive / PDF
Device & OS: not provided
Scenario: Multiple users attempt to collaboratively edit a shared PDF file stored on OneDrive.
Observed behavior: OneDrive creates a duplicate PDF file with a computer name appended to the filename instead of merging changes, due to a lack of real-time co-authoring support for PDF formats.

Before you start

Before troubleshooting, verify whether this issue occurs exclusively with PDF files. Microsoft Office files (like .docx or .xlsx) natively support real-time co-authoring on OneDrive, whereas standard PDF workflows do not provide simultaneous editing capabilities.

Solution 1Recommended

Establish a Manual Check-Out Protocol

Since OneDrive cannot merge simultaneous PDF edits, establishing a clear communication protocol ensures only one person edits the file at any given time.

Because the standard PDF format lacks real-time collaborative editing natively on OneDrive, any concurrent saves will trigger a sync conflict. OneDrive resolves this by saving a second copy to prevent data loss.

Communicate before editing

Notify your team via your preferred communication channel (like Microsoft Teams or Slack) that you are opening the PDF file for editing.

Rename the file temporarily

Right-click the PDF in OneDrive, select 'Rename', and append '[In Use - Your Name]' to the filename. This serves as a visual lock for other users.

Revert the filename

Once you have finished your edits and saved the file, right-click it again, select 'Rename', and remove the '[In Use]' tag so others know it is available.

Alternative Method: If you are using OneDrive for Business integrated with a SharePoint library, you can enforce the 'Require Check Out' feature in the library settings to automatically lock files during editing.

Solution 2

Convert the PDF to a Supported Office Format

Convert the PDF into a Word document to utilize OneDrive's built-in real-time co-authoring features.

Convert and Co-author Seamlessly with WPS Office

Frequently Asked Questions

Why does OneDrive append a computer name to my PDF file?

OneDrive appends a computer name when it detects a synchronization conflict. Since standard PDFs do not support real-time co-authoring, if two users edit and save the file simultaneously, OneDrive saves both versions to ensure no data is lost.

Does OneDrive support real-time co-authoring for PDF files?

No, real-time co-authoring in OneDrive is primarily supported for Microsoft Office file formats like Word, Excel, and PowerPoint. PDFs require exclusive access (one user at a time) to prevent sync conflicts.

Can I lock a PDF file in OneDrive so others can only view it?

Personal OneDrive accounts do not have a native 'lock' button for individual files. However, if you are using OneDrive for Business or SharePoint, your administrator can enable the 'Require Check Out' feature in the document library settings to prevent simultaneous editing.
