.CONF File Association 2
A CONF file is a configuration or "config" file used on Unix and Linux based systems. It stores settings used to configure system processes and applications. CONF files are similar to .CFG files found on Windows and Macintosh systems.
Most users will not come across a CONF file unless they are looking to modify specific settings. If you need to open a CONF file, you can use TextMate in macOS or GNU Emacs in Linux.
Some examples of configuration files include rc.conf for the system startup, syslog.conf for system logging, smb.conf for the Samba server, and httpd.conf for the Apache Web server.
httpd.conf - The Apache HTTP Server configuration file containing "directives" that configure what features are enabled for the Web server. It is often located in the /etc/httpd/ directory on Unix-based systems.
