I have 2 files (text) that I want to load into my DB (SQL) table.But my both the files have dupes in them (primary key dupes and duplicate rows).So how to eradicate or eliminate dupes from files before loading it to DB in SSIS packages.

Can some one tell me in detail what all the tasks (Controlflow task and Data flow task) I have to include in a SSIS package to achieve the above task?

I had to do that recently inside an SSIS package. I used the sort transformation and checked the box to "remove rows with duplicate sort values".

This is a pretty good article on how to do that.
