There may be a need to store files outside of K2 Smartbox SmartObjects. In this example SQL will be used to store the File and Smartforms will display metadata and the file.
1. Create a SQL Table with a varchar(max) property. Make sure that there is a Primary Key column on the table to allow for CRUD methods.
2. Create a SmartObject from the SQL Table. Change the varchar(max) property to be a File property instead of text in K2 Designer.
3. Create an Item View from the SQL Table SmartObject.
4. Test the View and ensure files can be uploaded and downloaded.
