Hi David,
I think you need to take a look at the ‘Directory Parse’ option under the FileSet/FTP Local Protocol Properties and make your own tcl-proc for it.
When using the ‘Directory Parse’, the incoming message is a list (ofcourse!!) of all the files found during the ‘scan’ of the specified directory. You can then sort this list and send it on into the engine, so the files will be read in the sorted order.
Hope this helps!
