So I'm a new user to the Creative Cloud, but I've been using InDesign for years. In the past, when my co-workers and i were working on an ID file on our server, if one person was using the file, there would be an IDLK file created to indicate the file was in use and that no one else could use that file. We just assumed that the same thing would be true on the Cloud, but we've found that it is not. Two of us have had the same file open at the same time. We are still just using test files, so nothing bad happened. But we would like to solve this before something does. Is there a way to indicate on the cloud that a person is using a file so that others won't try to use it at the same time?
