Hi Janel, When you use the built-in recorder you can make a recording up to the available amount of memory you have.
Also, you can record onto a compact-flash card or other external card if you like. You can also vary the quality of the recording you make and this will also effect the size of the final file. The format used is .wav which is apparently standard for this sort of thing. With all the variables, it is really hard to answer your question more specifically. Don
