what is default downloaded path in scrapy?
The response contents in parse(self, response) method are not files and are not stored on disk. The response is a python object and is stored in memory.  
Scrapy only downloads contents if HTTP_CACHE_ENABLED setting is set and it will cache all pages in <project_root>/.scrapy directory.
I have given a download file url in parse method, what is the default location for that files and Is there any possibility to change that downloaded directory?
