I am evaluating Fling File Transfer 2.35 Free, and possibly want to use purchased version if it is otherwise successful tests. I have come across a "problem" with one of my Windows directories that contains more than a douzen sub folders, and the base folder contains some 700 files at least 20 diffferent types... System with all those files cannot be configured otherwise and there is just ONE file that needs to be transferred to the FTP-site. Is there some kind of "shorthand" to filtering out all subdirectories and all files except the one that needs to be uploaded - without having loads of error messages? How many subdirectories and file extensions can be excluded - it is so tedious... /Bagtjesen
