location of file downloaded with WWW

Hi , I download a file using WWW and want to use that file some other time in my application. The problem is how can I get the location of that file saved in my local storage so I can then use it without any need to download it again.

You can use this function if you are downloading AssetBundle:

See also Caching class:

If you aren’t working with AssetBundle files you should save and check file existence yourself.
Use System.IO.File class for checking/saving/loading file. Save file in Application.persistentDataPath directory:
