What is htaccess? Why do we use this and Where?

[chinmay.sahoo]

.htaccess files are configuration files of Apache Server which provide a way to make configuration changes on a per-directory basis. A file,
containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and
all subdirectories thereof.

A .htaccess (hypertext access) file is a directory-level configuration file supported by several web servers, used for configuration of site-access issues, such as URL redirection, URL shortening, Access-security control (for different webpages and files), and more.
