We have a client with Server 2008 installed and running a couple of applications that don't support file locking. So one user can be using a certain file and the system will allow another to access it. The problem is that the editing is not in real time so the commit only happens when the user closes that file. When two or more people are editing the file at the same time, when the first one exits his changes are saved. Now when the next exits his commit replaces all the changes the original editor made saving only the new edits that user had made and so on.
My question: Is there a way to lock a folder (not just a single file) so that while one user is in it then another is denied access until the first user closes that folder? i.e. Only allow one user at a time to access any given folder(s)
