How to correctly set up VS working directory on Windows for project with multiple subfolders?

Tooling VS Code
8

For posteriority I record the solution, which turned out to be simple:

Note that my path structure was:
-Main folder
–Subfolder 1
–Subfolder 2

The Julia code lives in Subfolder 1, while the data the Julia code calls lives in Subfolder 2.

Through “…/”, the relative path goes up to the main folder first. By making Subfolder 2 the current working directory, all relative paths work as intendend.
