Shared viewModel between Directory

[shamshadpattani]

I am new to KMM. My question is, why do you create a separate directory, like a 'Photo' directory, for each function? Do you mean creating them separately? For example, if I need a login, should I create a 'Login' directory?

What is the real purpose of this? Is it for separation of concerns, or is it simply to use Koin? What should we do if a ViewModel is shared between both Login and Photo?
