+== Clarification of Terms Used
+
+* *Polling* +
+Polling is defined as the task where the Desktop app queries the server for changes - among other things. If the server responds with a change that had happened on the backend, the client will start syncing the changes after polling has finished.
+
+* *Sync* +
+Syncing is defined as the task where any changes will be synchronized, no matter if they occurred in the Desktop app or on the server side. Syncing does not depend on former polling while polling can result in a sync.
+
+* *Local Discovery* +
+Local discovery is defined as the task where the Desktop app looks for changes on the local filesystem. A local discovery can internally be enforced to check for changes that have been missed for example when the Desktop app was shut down during ongoing changes on the local filesystem. Any changes identified on the local filesystem trigger a sync after local discovery has finished.

 == VFS for Windows Server
 
 Without claim of completeness, actuality or support, Windows Server releases that are based on builds starting with 1709 should come with the native system API that is required to use VFS. Windows Servers 2016 and lower do not have native VFS included and will not be able to use VFS therefore.
