Many thanks, all! It looks like I was making a false assumption. When I read the documentation: "ExportConverterN may run a program using the following syntax (for example) ‘notepad %f’, where %f=filename, %m=modality, %s=stationname, ..." I assumed that I could use the same folder-making syntax that FileNameSyntax uses. A fortuitous misunderstanding because you've also given me a method for superior jpegs. Thanks again!
