In the TrueFire 3 desktop app there are two ways to access the PDF, MP3, GP5 assets included in the purchased course.
Access from Individual Course Video Lesson
First, when watching a specific course each video lesson will display the appropriate asset if applicable. Please note, not every video lesson will include an asset.
Jam Track - plays the MP3 jam track
Chart - opens the PDF chart in a separate window
Tab - opens the Guitar Pro file in a separate third-party software (i.e. TUX Guitar or Guitar Pro).
Access in bulk from Storage
Alternatively, you can go to Username > Storage (top right). Locate the course in question and click the "Folder" icon to view all the files downloaded to your computer from the course. Select the desired files as needed.
