How to Uninstall Drupal

Open an FTP connection with your Web server. Almost all Web hosts offer this type of file directory access through a FTP browsing application. This application will allow you to connect to your website's files with a user-created password and sub-domain connection path, such as 'ftp.yourwebsite.com,' for example.
Find the folder in your website directory where you created the Drupal installation.
Delete this entire folder by selecting it in the file browser and choosing 'Delete' from within your FTP application. This will remove all of the Drupal administration functions and all of the files associated with your Drupal-based website.
Open your Web browser and navigate to your website hosting control panel. This is usually found through your Web hosting provider's user area.
Find your database control area, and open it to get access to all of your databases.
Remove the database you created for Drupal when you first installed it. Drupal should be fully removed from your website.
