For each synchronization rule you can specify a method by which the file or folder should be synchronized between the server and the device. You can choose among three different ways to synchronize files:
With this method, the files to which the current rule applies are synchronized to the device. The files will not be updated on the server, even if they are changed on the device. Be aware that if a file is changed either on the server or on the device, the version on the server will be synchronized to the client again, overwriting any changes on the device.
With this method, the files to which the current rule applies are synchronized to the device at the first sync. At subsequent synchronizations, each file on the server will be compared with its counterpart on the device. If any change has been made to a file, the newest file will overwrite the older, regardless of where the file is found. This corresponds to the regular synchronization of calendar items.
Note that if a file is added manually to the device file store, the file will be synchronized to the server and become part of the current file sync rule.
This method corresponds to the one-way sync method above. However, after synchronizing, the file is opened on the device by the application associated with the file type in question, or the operating system if it is an executable file.
