Open directories aren't always a mistake. They serve several functional purposes:
To disable indexing across your entire server, locate your main configuration file (often httpd.conf or apache2.conf ) and change the Indexes directive to include a minus sign: Options -Indexes Use code with caution. index of files

Despite the risks, there are legitimate ways to use "index of files" for research, archiving, and data recovery.
