Combining multiple flat file into one using SSIS Package

Question

I have 2 files, which is data file and trailer file. I would like to combine these files using SSIS package generated by asp.net program.

To combine the two files, i tried Union all but the duplicated rows will be replaced, I also does not wish the data to be sorted like in merge function. Is there any other way i can combine the two files without doing any filtering, just with copy and paste into a new file?

Thanks

Union All Transformation doesn't remove duplicates, make sure you are using this component correctly.

You can refer to the following tutorials for a step by step guide:

If you are looking to remove duplicates, you can refer to the following guide:
