>While I am not sure how to solve it, let me comment on why the error appears. The FOR EACH is executed once for each file, but there is no guarantee that there is any. The TRY part might have other instructions, outside the FOR EACH loop, that may trigger the CATCH part. In your code, there happen to be no more commands, but the compiler probably doesn't notice that.

Thanks, this has resolved the issue.
