Footsteps on a wooden floor? New session from workplace

Decided to set up my cam and digi again at work.

Have gone through 3 hours of the digi recording so far and found this...

It sounds like footsteps on a wooden floor, there is a bit of echo in each step which makes it sound like an empty or large room. You also hear what sounds like a door latch. An enhancement will be greatly appreciated.

I'll have a go today if I get time, maybe lunch time and post it back if thats OK
