How to implement "Universal configuration file for applications"?

Question

Data storage

Greetings!
I will describe the question:
{
Problem:
I work on two laptops (Win10), they have various applications installed - from SublimeText to PhotoshopCC, when I work on one laptop and change some settings in the application, then I have to re-register these settings when I switch to the second laptop. ..
Starting from this tedious idea, you need to figure out how:
Develop a utility (ala synchronizer) that pulls the configuration from the application and saves it (with the configuration extension) into a separate file in the general configuration directory and throws it, for example, on Dropbox.
}
Actually the general question is - how would you solve this problem?
+ An additional question about the "universal configuration file" - how to create (how and what file format to choose) to write all application configurations into one file?

Answer 1

It will be too confusing to keep track of the zoo of all kinds of configurations and synchronize. Before updating, the synchronizer will have to somehow resolve conflicts in the configurations.
