BLOB setting

[riscanuc]

Hi,
I use the the query:
SELECT c001 AS filename,
c002 AS mime_type,
d001 AS date_created,
n001 AS file_id,
blob001 AS file_content
FROM apex_collections
WHERE collection_name = 'DROPZONE_UPLOAD';

What is the setting of the file_content column in order to download?

I know how table down load works, but don't know how apex_collections download?

Thanks
