Can I have SFTP access?
No.
The my.vanderbilt.edu platform is a dynamic environment – which means there aren’t any physical folders that you can SFTP into. Everything is dynamically built from a database. The folder that your site lives in doesn’t exist as a physical folder on the server. It’s dynamically created.
The only files that physically exist on the server are images, pdfs and word docs that are uploaded through wordpress.
