We use PDFCreator to write a PDF to a file which is picked up by an FTP process every 15 minutes. Additionally every 15 minutes (1 minute before the FTP) we copy files from the Autosave folder to an archive folder. I'm guessing we are getting the above mentioned error because one of these processes is grabbing a file that PDFCreator is not done writing? Is there a way to use a batch command to pause PDF creator from writing for a certain amount of time? This error is causing a serious workflow failure.
