i came upon a business management app that has everything I need and want, cost is 999.99. My concern is that I'm about to put a large data base into it and am unsure of what would happen if the app crashed, got corrupted or wasn't o longer supported. Can you save files from apps to storage? As proprietary software, I'm unsure if it would migrate to other similar software. Perhaps these questions are answered by the developer, just interested in other's opinions and experience.
