What does back up option does? I mean, does it copy the entire image library to a folder or it save as 1 files?

Hello Sathana,

Thank you for posting your question, I will be happy to help you.

When you use our backup feature, it copies all the photos on your device ( camera roll / photos album ) and makes a backup on your computer. When you backup the photos, it will only copy the photos and not delete them.

Please let me know if you have any other questions! Note: we have some great walk throughs on our website as well that demonstrate and show what our app does: www.phototransferapp.com/help

Best,
