I having an issue with something that should be simple, but I can’t find any documentation on it.

I have an Email Reader which is pulling out an attached file and posting the file to a new directory. I would like the directory to be dynamic based on the subject line of the email. For example:

Subject: client

Post the file to: [abc.com/client/incoming/#](http://abc.com/client/incoming/#)

I am saving the Subject as metadata and also writing it to a text file. Is there an easy way to either reference the metadata in the URL string or create a parameter from the metadata so it can be used in the URL?

Thanks,  
Laura

Hi Laura,

This is easily possible using [partitioned writing](http://doc.cloveretl.com/documentation/UserGuide/index.jsp?topic=/com.cloveretl.gui.docs/docs/partitioning-output-into-different-output-files.html).

Example:

File URL: ${DATAOUT\_DIR}/#/email.txt  
Create directories: true  
Partition key: subject (The name of your metadata field)  
Partition file tag: Key file tag

I hope this helps.
