To access your library, first go into "Settings" in Rocket Player.
Select "My Library" in the "Settings" menu.
To designate which folders to scan, "Select Media Folders".
Here we see our storage path location(s). To bring down our specific files located within the location's path, press the storage.
When you bring down the storage path you now have access to all of our folders within our device. Some folders are already selected within the storage. Select the folders where your music is located. If you have a ringtone, notification or other unwanted item, deselect the folder where it is held and it will be removed from Rocket Player's library.
