Adobe Collaboration Synchronizer

[Kerc]

Hello,

Adobe Collaboration Synchronizer seems to prevent me from moving Acrobat(PDF) files right after I opened then, and than closed them. I get the message that "it's still in use with another program". But it's closed - no program open!

I have to either completely reboot or via task manager end the process "Adobe Collaboration Synchronizer"

Only then can I move an AcrobatPDF\ file.

Very anoying!

Is there a way to eliminate Adobe Collaboration Synchronizer permanently without jeopardizing functionality of Adobe?

Hello! I just wanted to thanks for the information, it is accurate I used to have the same irritating problem, then I followed the procedure, and now it works perfectly. Thank you so much for helping us.

Unfortunately, AdobeCollabSync.exe is one of Adobe's worst irritations. At work, we use software that regenerates PDFs frequently. However, on the second attempt at generation, the program says it cannot access the folder. This is despite the fact the PDF file was closed in Acrobat DC, and even Acrobat DC itself has been closed! A quick check in Windows Resource Monitor shows that AdobeCollabSync still has a handle on the file or folder [in the CPU tab, search for your file/folder name in the Associated Handles "Search Handles" box]. Stopping the AdobeCollabSync process in Windows Task Manager instantly allows our program to rewrite its PDF files again. The semi-permanent solution is simple:
1) End the AdobeCollabSync process in the Details pane of Windows Task Manager.
2) Go to C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\ and rename AdobeCollabSync.exe to AdobeCollabSync-JUNK.exe.
3) Click the Windows Start button, type Startup, and select Startup Apps. Turn off AdobeCollabSync.
Note that if Acrobat DC receives an update, it will reinstate a new copy of AdobeCollabSync.exe, so you'll need to repeat the steps above.
We have had no ill effects from suppressing this irritating process, so we can now happily generate our PDFs without Adobe Acrobat's historically poor file handling interfering with our work.

AdobeCollabSync.exe seems to lock random files - even if I didn't touch those files or open the Adobe app in the current session. I use the Adobe cloud syncing which I assume relies on AdobeCollabSync.exe, so I don't want to permanently disable it. Instead, I have a batch file on my desktop which runs the following command:

taskkill /im AdobeCollabSync.exe /f

So whenever I run into locked files, I just double-click the batch file, and the problem goes away - until the next time I use the Adobe app or reboot. Strange that Adobe still hasn't fixed this.
