You’ll want to read my previous post Moving SharePoint List Attachments to the File System, to get all the details and requirements for setting up and running these SSIS script tasks.

This is an SSIS Package code which will iterate through the document library to get some relevant information about the documents, and then move specified documents from a document library to the file system.

I will just explain the two script tasks steps, as the rest will be specific to your task.

You can use a Script Task in SSIS to move SharePoint list attachments to the file system.  This C# code references the Microsoft.SharePoint assembly. It’s very important to note that the the SharePoint attachments have to be on the same server that the package is running on.  Thes means that the package can only run on SSIS installed on the SharePoint box where the attachments are.  You will need to install SSIS and the corresponding msdb database on your SharePoint server if it isn’t already installed.

This is what the final package looks like:

Most of the these tasks are self explanatory and you’ll need to set up your own tables and logic to accomplish the goals of your package.  You’ll want a table that tells you which items have attachments.  See this post for details on how to import data from a SharePoint list.  Attachments is one of the fields you can import, which is simply a bit that says whether or not the list item has any attachments.

These are the variables used in the package:
