Delimited Text Driver , output CSV

Hello,

I am new to Delimited Text Driver

For publisher implementation it's ok, I have done so many

But for the subscriber, I am intending to perfom an extract of some User data daily on a 'sync' operation

My question is how to implement writing to the file in "creation" & "placement" part of the subscriber as we have no DN ??? if you can give me some DirXML examples

I want to do a daily extract and suffix the file by the timestamp (example: output-23-12-2011.csv, output-24-12-2011.csv, ... ) how to acheive that ?

Thanks in advance
