Jacqueline, Thanks for the suggestion,
still 'the result' after execution is empty. It would probably contain
something if path selection failed. The other 'result' (path stored in
'it') does not always contain an extension. If user types it in, or
chooses from a list of existing file names, then it is there. But
otherwise if user provides file name without an extension, script has to
check what was the file type selected, appends correct extension and
directs output to a necessary processing handler. It knows file type
just because it asked about it before asking for the path. Now I guess
if I wish to avoid displaying a chain of dialogs, I have to design own
custom askFile() function or handler. The only role of ask file with
type or ask file with filter that is described in the dictionary seems
to be limited to displaying existing filenames whose types match the one
selected in the file type list...
All the best!
