Desde la versión 9.50 de Opera se eliminaron las extensiones de los ficheros de la caché, cosa que dificulta enormemente la búsqueda de cosas en la caché.
Es posible añadir a opera:cache vistas en miniatura, búsqueda y ordenar por nombre de archivo y tamaño, para facilitar la navegación por la caché.
La manera de hacerlo es la siguiente:
- Copia el fichero de idioma (*.lng) que utilices (normalmente se encuentra en la carpeta locale, en el directorio de instalación de Opera).
- Abre el fichero de idioma con un editor de texto y reemplaza la línea -1713924769 por esto:
- Accede a Herramientas, Opciones, General, Detalles, Idioma de la interfaz de usuario, Seleccionar y escoge el fichero que acabas de modificar.
- Reinicia Opera.
- Accede a opera:cache y comprueba las nuevas funciones.

AVISO: al acceder a opera:cache y utilizar estas mejoras puede ralentizarse mucho el ordenador.
