"File Path Control" default Value

[Hooovahh]

As Darin mentioned, on other platforms an empty path is valid.  Try using the List Folders function with an empty path, what does it return?  A list of current drives.  If you provide a Not A Path it should error.

In my mind this is the same as supporting the NaN (not a number) for doubles.  Why support this when you could just have the default be a 0 and use the Equal 0? to determine if the user didn't enter anything?  Because 0 is a valid value for things, just like an empty path can be valid.

Why don't we have the Not a String value?

I can't really see a purpose for it, or a use where I could use a string which has a value of "Not a String".  I'm guessing that's why one doesn't exist.

Usage would be the same as for Not A Path - to distinguish between an unwired terminal, and one that has an empty string wired to it.
