#include path to a parent folder

Hello, I have a problem using #include statement. I want two sketches to use the same header file, placed in a parent folder of both sketches folders(instead of having copies of that file in each sketch folder).

But I could not find a way to describe a relative path to a parent folder in the #include statement.
I tried this

#include "../adresses.h"

and this

#include "..\adresses.h"

but it didn't help.
So I had to specify a direct path to the header file, like this

#include "D://adresses.h"

It works, but it's not what I wanted.
Can anybody here give me some advice on the subject? I would really appreciate any help.
Thanks.

What OS are you using? Why is the extension on addresses not shown? Why is the file, if it is addresses.h associated with Arduino as the application to open it?
