You have to use the "ask file with type" form to know the file type
selected within the dialogue, for example:
ask file "" with type "PNG file|png|PNGf" or type "Plain file|txt|TEXT"
put it && the result
/Users/bvg/Desktop/file.txt Plain file
Most likely "ask file with filter" will be marked as obsolete or
discontinued in a not too distant future...
