Lista de extensiones de archivo
Una extensión de archivo es el grupo de letras después de un "punto" en un nombre de archivo. La extensión indica el formato o el tipo de archivo. Por ejemplo, en el nombre del archivo "readme.txt," la extensión "txt" denota un archivo de texto que se puede ver usando un editor de texto como Notepad o Word.
Los sistemas operativos, como Mac OS o Windows, utilizan la extensión de archivo para elegir que programa abrir cuando un usuario hace doble click sobre un archivo.
