How to Stop Adobe Collaboration Synchronizer from Locking PDF Files
Question details
Users are experiencing issues where Adobe Collaboration Synchronizer continues to run in the background after closing the application, which locks PDF files and their folders, preventing users from renaming, moving, or deleting them.
- Product
- Adobe Acrobat
- Device & OS
- Windows
- Scenario
- Attempting to organize, move, rename, or delete PDF documents and their containing directories after working with them in Adobe Acrobat.
- Observed behavior
- PDFs and their folders remain locked by the AdobeCollabSync.exe background process, and pausing synchronization via Adobe Creative Cloud fails to resolve the issue.
Ensure you have saved all changes to your PDF documents and fully closed Adobe Acrobat before terminating background processes or modifying application files.
Terminate Process and Use Administrative Settings
The safest standard approach to unlock your files is to end the synchronizer task manually and adjust your software administrative settings.
Ending the background process provides immediate relief so you can move or delete your PDF files. For a long-term fix without deleting system files, adjusting the collaboration settings via Adobe's administrative policies is recommended.
Press Ctrl + Shift + Esc on your keyboard, or right-click the Windows taskbar and select 'Task Manager'.
Navigate to the 'Processes' or 'Details' tab and look for 'AdobeCollabSync.exe'.
Right-click on 'AdobeCollabSync.exe' and choose 'End task'. This will immediately unlock your PDFs and directories.
Consult your IT administrator to disable background collaboration features via Adobe's administrative templates or Windows Group Policy to prevent the service from starting automatically.
Rename or Delete the Executable Files
Advanced users can physically rename or remove the synchronization executables to prevent them from launching, though software updates may restore them.

Frequently Asked Questions
Why does Adobe Collaboration Synchronizer keep running after closing Acrobat?
AdobeCollabSync.exe is designed to handle background synchronization for document reviews and cloud-based team collaboration. It remains active in the background to ensure files are continuously updated, which can unfortunately lead to files and folders remaining locked.
Will pausing synchronization in the Adobe Creative Cloud app fix this issue?
No, many users report that pausing synchronization within the Creative Cloud desktop application does not stop AdobeCollabSync.exe from running in the background or locking directories.
Is deleting AdobeCollabSync.exe a permanent solution?
Deleting or renaming the executable is highly effective in the short term, but it is not completely permanent. Subsequent application updates or running the Adobe repair tool will typically download and restore the missing executable files.
