How to sync a subdirectory of a git repo?

Question

I want to pull from and push to only a subdirectory of a git repository. Here is an example of what I want to achieve:

Let's say, I have a repository, containing two folders A and B (they are top-level folders, if that matters). I want to work and push changes into B only, while others are working on A and maybe even on B as well. Because I want to commit my changes back, I can't put A in the .gitignore file, nor I can use git rm -rf --cached A, since A is needed by others, however, I know, I will never touch any of the files it contains, and I simply don't want to store the unnecessary files of it. I can't use submodules either, as I don't want to change the original repository, nor I want to maintain a secondary one.

So my questions are: is this even possible; and if so, how can achieve this?

Answer 1

You can't pull or push from a specific folder in your repo. You pull or push on a branch.

Have you considered making a branch and switching to it when working on B, this way, you won't pollute your team's work made on A ?

You could even rebase your branch if you want to retrieve the work made by your team on the main branch to your own branch.
