Dotfiles are files that usually live inside the dot directories (hidden directories) or are dots themselves (again, hidden). In Unix and Unix-like Operating systems, the dot(.) at the start of the file/folder name flags it as hidden by default. Configurations and personalization files are usually put as dotfile or dot directories, *which again, makes it hidden*. Hence the term "dotfile" was born.
