I have link in a rst file that refers to a local file, which will be in a path dependant on user name, such as:

`The link to my file <file:///C:\Users\USERNAME\AppData\Local\Apps\myfile.html>`

I am on a Windows OS, and this is a typical path that can be accessed with %APPDATA% in Explorer.

I would like to provide the link with something like:

`The link to my file <file:///C:%APPDATA\AppData\Local\Apps\myfile.html>`

My try with %APPDATA% did not work. How should I do?
