If you are trying to append all of your files you have gather into 1 file, and for sake of argument they are all to be text files, then you probably want to create an "Execute SQL Task" object. In there you could use an
EXEC
master..xp_cmdshell 'COPY C:\WhatEverDir\*.txt AllFiles.txt'
Is this what you are after?
