Hi All,

I want to run a graph which reads a set of csv files. My problem is that this set of files is generated at runtime (I cannot express it as a regular expression since I do not know exactly which  
file I will read).

Is there a way to “tell” the reader which files to read at runtime ?

Thanks

Hello,  
you can feed the DataReader with file names to read with input port (see [Input Port Reading](http://www.cloveretl.com/documentation/UserGuide/topic/com.cloveretl.gui.docs/docs/input-port-reading.html)). The set of URLs you can prepare in [DataGenerator](http://www.cloveretl.com/documentation/UserGuide/topic/com.cloveretl.gui.docs/docs/datagenerator.html) and send it to DataReader similarly as described in [Process only unprocessed files](http://forum.cloveretl.org/viewtopic.php?f=5&t=2346).
