How can I backup my edited files?

By using iTunes's backup, all of Piascore's data is backed up.

So you can transfer the data to other iPads / iPhones (for recovering iPads/iPhones)

(If you want to transfer all data to another device, please see How to transfer all data to other device)

1. Updates your Piascore to the latest version
2. Launches Piascore once after updating
3. Connects iPad to PC
4. Launches Finder or iTunes and backups all data on your iPad

5. Connects another iPad / iPhone to a PC
6. Recover the iPad / iPhone from the backup data
   • (Caution: after recovering, the previous data on iPhone / iPad will be erased)
