CentreStack is a managed file sync and share solution. It is different from other file sync and share solution in that it has client side drive mapping support, instead of having a sync folder.
When it comes to client side drive mapping, a native benefit is file locking.
Many other file sync and share solution is built on top of folder synchronization. With folder synchronization, it is not easy to do file locking, nor file permission because after the file is synchronized to local machine, the user has full control.
With drive mapping support, like CentreStack’s client applications does, it is possible to do file locking. Because the request for the file first reaches the drive , and the drive can decide what to do first before the request goes to the real file.
