I am a beginner working on Windows 7. I installed Acquia Damp Stack about a year ago, downloaded an instance of drupal core 7.9 onto my desktop, and created a new site and database, a subdomain that I named 'drupal-sample1.localhost' . I played around with some of the features and abandoned it. Now I am back and want to update to the lastest version...7.17 and start all over. I have no attachment to my test site so I want to delete it. Since the previous version 7.9 is on my desktop, can I delete it and download the latest version? The plan would be to save the latest version into 'user\mark\sites\drupal717'. The database is also a sub that I am hoping to delete. Does this make sense? Thanks for your feedback.
