"Open in another Program"

Hi All,

I cannot delete or change file names - "file is still open in another program" ... even though PS or any other program is closed.

Now I have to go to Task Manager > Processes > and stop Adobe Content Sybchronizer and/or Acrobat Collaboration Synchronizer ... depending.

Only then can I delete or change file name.

Is there a way of avoiding this? Can these Synchronizers be changed in behaviour or can they be turned off or eben deleyed? How important are they for other purposes?

Thanks in advance for any tips or solution
