How to implement synchronous file editing?

Question

Code editor

Essence:
I write a module for one cms and check it on it. I have a copy of this module (an install, so to speak), that is, all its files, taking into account their nesting in folders.
Let's say I corrected 10 files in my module inside the engine.
Question:
What is the most convenient way for me to transfer these changes to my copy? It is desirable, of course, that this is generally done automatically and files are edited simultaneously both in the copy and in the engine.
ps I use sublime text to edit the code, if it has such a feature, then tell me where and how it is enabled.

Heard anything about git or svn?
