How to use File Adapter Receiver to write attachments

Question

Hi,
i have a scenario, in which our own XInotes adapter sends an XIMessage from an IBM Lotus Notes database into XI. This XIMessage contains an XML document as application main document and several PDF files as additional attachments 
On the receiver side, i must use a File Adapter to write both the XML documents and the PDF attachments into a directory.
The problem is i don't know how to use the file adapter receiver to write the attachments. In the Channel Monitoring, i can see that all PDF files are transferred to the file receiver. But the file adapter writes only the XML document into the directory.
I've also tried the AF_Modules/PayloadSwapBean, but it can only swap one PDF file into the application payload. And the file name must be hard coded in the module configuration as swap.KeyName.
Could anyone give me any ideas?
thanks a lot in advance

hi,
receiver file adapters do not supprt attachments.
Only File Sender adapter is capable of handling attachments not the receiver.

Configuring the sender FILE adapter
The sender file adapter is configured to pick the normal payload (file1.xml), which is specified in the File
access parameters, and the additional image file (file1.jpg) that is to be sent as an attachment is configured
under the Additional File(s) as shown in the screenshot below. The file type would still remain binary.
Since, by default, XI sends payload and attachments in XML format, we need to call two beans, namely the
MessageTransformBean and the PayloadSwapBean to help us is transforming the content to jpeg format
and also change the file extension.
The PayloadSwapBean module is used to replace the application payload of the XI message that holds the
data with another payload which is appended to the message as an attachment. In our case, the payload
would be file1.xml whereas the attachment would be file1.jpg
The swap module is denoted in our scenario with the module key ‘swap’. It has two parameters from the
MIME header.
