We are having a problem where 2 people open the same Pro/E file and then one saves over the other's changes. We are running Pro/E Wildfire 3.0 on Linux. I know that Linux and Unix don't do automatic file locking like Windows. But most other applications that run on Linux/Unix check files themselves. Can Pro/E do this? Is there some fix? (We are not using data management system at this time. Just storing files on the network in directories.)
