Как известно, в последних версиях Opera у файлов в кеше убрали расширения, что повлияло на способ извлечения некоторых файлов (например видео ролики, которые стандартными средствами сохранить на диск не удаётся).

English:
This software designed to parse (and sort) Opera's cache files!

As most of you already knows, in the last opera versions it's become almost impossible to pull out cached files, since they not have file extension. Sometimes this process (puling out the cached files) needed to get some files that are viewed on the pages, for example videos, because standard methods not so practic in those cases.
