I'm hoping somebody can help me with a technical issue I'm trying to solve.

Essentially I am trying to build an fft analyser to measure the frequency components of audio files.

I currently have a groove object connected to an fft object, which is working well, but the output is in real-time. What I really want is an averaged fft over the entier length of the audio file.

I'm not sure of the best way of impementing this, but I was thinking if there was a way to break-out the fft bins, I could average these over the time period required and present the results once the time had been completed - or maybe there is an easier way, or maybe it isnt possible at all!

Look in the help menu for Help > Examples > fft-fun. There are some patches in there that show some ways of recording and manipulating fft frames. What you're proposing should be possible, although a bit fussy. Max is much more suited to realtime analysis.
