: This is a fundamental principle of secure web hosting. The web root directory (e.g., public_html , www , or htdocs ) is intended for public-facing website files only. All wallet.dat files, configuration files, and backups must be stored outside this directory.

If the administrator forgets to disable directory browsing or fails to configure an .htaccess file, web crawlers like Googlebot will catalog the folder. Storing sensitive data under the web root "creates
