Does anyone know data recovery library

I am preparing to build a data recovery app for Mac. It’s pretty hard to build the product from scratch(smilar one on the market, built with QT framework). The one is a paid and i want to develop a free one. :smiley:

Does anyone know third-party recovery app? C, C++, Objective-C are ok.


Data recovery ? even if i am not a expert. But i have a idea to rescue SMS,videos,contacts,photos back , if you are using iOS device , maybe my ideas can help you solve it
