In the architectural industry, we use AutoCAD drawing files that require only one person to open and edit the file. Most cloud storage options don't lock the file when it's being accessed. Other people are able to open and edit the file and therefore the cloud software doesn't know which file was the parent holder and instead updates the file based on the most recent changes.Even Microsoft's Dynamic Cache Service doesn't have a file locking feature. Therefore we need to use something called GlobalScape.
