Final Answer:
The best way to save and keep all of your added content would be export to external drive. Thus the correct option is A. Export to external drive.
Step-by-step explanation:
Exporting your content to an external drive provides a secure and easily accessible backup solution. External drives offer ample storage space, allowing you to keep your files organized without worrying about limited capacity. Additionally, external drives are not dependent on internet connectivity, ensuring access to your content even in offline scenarios.
Moreover, Ableton's cloud storage (option B) might be suitable for collaborative projects or convenient access, but it may have limitations in terms of storage capacity and privacy concerns. Saving locally on a computer (option C) is efficient but lacks the safety net of an external backup in case of hardware failure. Sharing via email (option D) is not a recommended long-term storage solution due to file size restrictions and potential security risks.
In conclusion, opting for an external drive provides a balanced approach, combining the advantages of ample storage, offline accessibility, and data safety. It ensures that your content remains protected and easily retrievable, making it the optimal choice for preserving your valuable additions over time.
Thus the correct option is A. Export to external drive.
