Are you using the URL form of file writing or are you opening the file, 
writing to it and closing it again?
I THINK, that if you use the URL command, it will overwrite the current 
contents of the file with whatever you specify, which can be anything, 
including empty
e.g. put empty into URL ("file:" & myFileName)
