where to put config file in VS Code

I am a beginner and have been googling a lot, I made a java project as part of my school assignment, I created a txt config file to modify the speed game size and number of snake available per game, all works well when I put the file under SRC on the IntelliJ project but I wanna use VS-Code but when I put this config file on a similar project that I created for VS-Code this config file doesnt work everything is on default, only 4 snakes and same game speed although I alter it.
Please Help. In which directory does vs code execute code from perhaps I gotta put it there but problem is I dont know and Please note I've been having this issue for long and did try googling the solution.
