I don't know how to do this with FileNameSelector, but it can be achieved with a combination of Button and SystemDialog["FileSave"] or SystemDialog["FileOpen"]. I have done this and found it pretty straight forward, so if you need more information I could try to find the code snippet, but probably you are faster rewriting it your way. The only pitfall I can remember is that you need to use Method -> "Queued" for the Button, otherwise the preemptive link is likely to time out... hth, albert
