 * _**const std::map<std::string, std::map<std::string, http::file_info>>** get_files() **const**:_ Returns information about all the uploaded files (if the files are stored to disk). This information includes the key (as identifier of the outer map), the original file name (as identifier of the inner map) and a class `file_info`, which includes the size of the file and the path to the file in the file system.
