I keep save files in a private directory in my iPad app, namely the one returned when I use:

paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
documentsDirectory = [paths objectAtIndex:0];
documentsDirectory = [documentsDirectory stringByAppendingPathComponent:@"Private Documents"];

Notice that I also append a subdirectory to it. When I update the app, users are telling me that their progress in the app is getting destroyed. Are files in this NSLibraryDirectory destroyed every time I update the app? If so, should I be using NSDocumentDirectory instead?

Additionally, is there no way to make a further update to my app to remedy this without destroying all my my current users’ save files? It doesn’t seem like there is.

    You should save them in the Documents folder, it is persistent across updates.

    Monotouch: documentsDirectory = environment.specialfolder.personal;

    Objective-C: NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)
