I did a Google search of your heading, without the "Re:", and came up with a number of results.

Actually I changed the heading to "File Open Dialogue - How to change folder choices on the left".

The first hit seems interesting. Not a solution to your question, but a replacement for the Word "File Open" dialogue.

The web site is at;

Go see what you think of it
