Just remember that by default, GetFolderItem looks inside the same folder as your application (or your project, if you’re running it from within the IDE), so you need to specify the full path to the file. Like this:
f = specialFolder.userHome.child("htmldocs").child("int.html")
(This is just an example: it will fail if you don’t have a folder called “htmldocs” in your home directory.You should enclose it with a try-end try and check for exceptions in case any of the file lookups fail.)
