Answer 1

As far as I know, the accepted answer is not correct as C14L indicates.

It can be done by opening a different folder that includes the folder you're working in. So say we have /project and /project/src and /project/build, you're probably interested in having src open in two instances of VSCode, which you can achieve by opening /project and /project/src.
