I notice that when I capture video, vegas creates both a M2t and a SFK file. The M2t appears to be the actuall video file, as it will play in WMP. What is the SFK file and do I need it if I was going to copy video from this folder and save it to another hard drive?

Thanks in advance for your replies.

The sfk is an image of the waveform for the audio so that Vegas (and other Sony products) can draw the audio waveform more quickly. If you delete it, it will simply be recreated the next time you open the file in a Sony product.

I was wondering the same thing Edward. Thanks for that excellent response. I would not have guessed it was audio related.
