Suggestion for overspill directory(ies)

[Agamemnon]

Is it possible to modify GBPVR so that it can include an overspill directory or directories for recordings if the primary directory located at "C:\Temp\" or wherever else gets full or there is less than 4 GB of space remaining or when using an external drive to set that as the default drive but for GBPVR to switch to a fixed drive if the external drive is not connected?

I have mine set up with a program in the postprocessing that sends an email when a set amount of space is left.
the email I gave it is the one for my cel phone, so I know I need to do something no matter where I am.

I cant remember the name of the program, and I am not at my server at the moment.
