Inside addCompanies.rst I have
Add Companies
=============
:ref: _my-reference-label:
adding
-----
ahdlkasdflk
This documentation will help you to add homes.
Now I am trying to link the file from another file change.rst in the same directory
Change company
=============
* How to add new company ? my-reference-label_
But the my-reference-label which I wanted to be a link is not producing any link.
What might be the problem here? Also what if I want to link the file from another directory file ?
The syntax you use above appears to be a non-sensical confusion of valid link syntax. You have the syntax for cross-referencing arbitrary links incorrect. This should remedy it and will work between files.
Add Companies

.. _my-reference-label:

Change company

* How to add new company ? :ref:`my-reference-label`
Also make sure that the underlines match the length of their text.
