How i can add a file with a widget in bonita?

Hi
1) how i can configure the widget of file in order to add a file and then insert it in a field of table using mysql query into connector?

2)I think that , when you upload a file , for then add in a insert query, you only adds a address into the filed of table , and then you have to copy manually this file and put it in a folder , is correct?

Regards
