Trying to access files in a sub-folder of my main project folder


I have a project folder called ‘IT4203’. In that project folder, I have a sub-folder called ‘INTRO’ which contains the file ‘introindex.html’
When I try to access that file via a link on my webpage I get an error that the file doesn’t exist.
How am I suppose to access the file?


Without seeing how you are attempting to do it, it’s very difficult for us to give you specific help. A screenshot would be best.
