Great Charles.
Thanks, I tried it and has replaced what I had.
Thanks again.

I have a new problem. That file was created by MyApp (Creator code aaAA) and 
has MyApp's icon. When double-clicked it opens myApp as expected but I want it 
to open another app, myApp2 which has bbBB as its creator code.
Is that possible?
Thanks again

Lennox

Only if you're lucky.  Here is some code that doesn't depend on luck.

dim f as FolderItem = DesktopFolder.Child("foo")
If f is nil then //something went wrong
   Return
End if

dim t as TextOutputStream = f.AppendToTextFile
If t is nil then
   //check f.LastErrorCode
   Return
End if
t.WriteLine "foo"
t.WriteLine "foo"
t = nil //the file is closed when the object is destroyed

FolderItem.AppendToTextFile creates the file if one does not already  
exist; presumably CreateTextFile fails if the file already exists.
