this should help......

If there are 10 different files each in different folder, I would suggest a script task with a C# script to delete a file and error out and fail the package(or howsoever you wan to design)

on error.

The other way could be :

Create a variable for path of folder....say src_path

Bring all your folders as resultset of a sql query....like

select 'c:\folder1' union select 'c:\folder2' union select 'c:\folder3'

Load it into a recordset destination(say the var rs)

Set Up a foreach Loop Container. Drive the iteration based on the rows contained in the recordset variable(look up help on ForeachLoop Container). Map the collection value on each iteration to the variable called src_path.

Set up a File System Task inside the loop container. Set The 'Operation' as 'Delete File'.

Drive the Source connection through a variable src_path

This way, upon completion of the loop, all your fiels ahould be deleted.

Hope this helps.
