Currently, our player uses indexing. The player only scans and indexes all the files if one of these conditions is met. It will scan through the database and indexes all the files during the initialization (boot up) or if a new storage is detected. Adding a file to a shared folder does not meet one of the two conditions above; therefore, the player cannot see that file. If you don’t want to reboot, what you can do is to go to the Settings->Shared Network and add the shared folder again.
