Variable\Switch data file

Which .json file stores the variables and switch in a game project?

Please explain what exactly you're looking for - values are never stored in json files, and the names of the switches have no function ingame, so what exactly you want to know or do from there?

But there is no variable\Switch Data files in rpg maker

When I set up an event with a variable or a switch, and I want to import the whole switch\variables list names, which file should I copy to the new project folder?

It seems to be part of System.json, where all the Database terms, sounds effects etc. are stored as well. You could try opening both the old and the new System.json file in a text editor and copy over the parts of the file that read "switches":[..........] and "variables":[..........]. Make sure to backup the files before you attempt this!

Ohh now I understand,if you use Rpg Maker Vx Ace then "Go to you're Project-->Data-->Commen Events File it is the file where all the switches
/virables are stroed..

Thank you!!!

My Pleasure.
