How do I Open file from a path on Linux/osx with NWjs?

Hello!

Here is my question. I know how to do this on windows. Not on linux and osx. Basically I want to open a nw.js project using another construct 2 nw.js project (loader) for that. It works on windows like this:

Use the file open event:

nwjs.AppFolder & "folderinside\file.exe"

It opens file at *\folderinside\file.exe, where "*" is where the "loader" file is. It works.

I am not sure how to do that on osx and linux. How does the file path look like on these systems?
