Installed network into wordpress folder but want to remove 'wordpress' from url

Hello,
I am running a network installation of wordpress that currently resides in a wordpress folder (ie. impactmovement.org/wordpress/…). I would like to keep the folder structure but eliminate ‘wordpress’ from the url. Is there a way to do that over the entire network w/o moving the network to the root folder?

I have already tried moving the index.php file to the root folder which removed ‘wordpress’ from the home page, impactmovement.org/wordpress making the url impactmovement.org but the rest of the pages and posts had wordpress in the url.
Thank you for the assistance.
