I don’t know the answer to your question, but you can set things up so that Git ignores those files in all projects: https://docs.github.com/en/get-started/getting-started-with-git/ignoring-files#configuring-ignored-files-for-all-repositories-on-your-computer

What do you mean by "buffer files" and "specific Emacs' files"?

As an example, all this tilda files. I could certainly gitignore them but is there any better way of saving these files in a specific folder outside each project folder?

Are you using a pre-configured Emacs distribution similar to Doom/Prelude/Spacemacs etc. I am using Doom and this has never been a problem for me. I think Doom configures Emacs to put all extra files to a special directory and not in the current directory alongside your project files.

I’m not using any distro. I’m configuring Emacs from scratch to fit my needs. In the future I might use Doom but for now I think this is a great exercise. :thinking_face:

I know Doom handles this out-of-the-box (someone told me, not that I know by experience).

https://www.emacswiki.org/emacs/BackupDirectory might be relevant to you.

Oooh, that’s exactly what I need! Thanks @UJRDALZA5 🚀
