path to scripts folder

Hi,

am i right to assume that this:

var scriptsFile = new File($.fileName);
will cause a problem in running as a script as binary (because of the $)

and if so

is there a way to find the scriptsfolder, other than

var scriptsFile = app.scriptPreferences.scriptsFolder
because that takes you to the scriptsfolder in the Library/Preferences, and I want to end up in the app folder.

Just to clarify: I don't want my client to be able to accidently open the script by doubleclicking on it, so I want it to be a binary. But i need to figure out where it is in order to find some datafiles.

Thanks,

james
