Interpreting a direct path read wait

I am attempting to interpret a 10046 trace, looking at a line that says:

WAIT #1: nam='direct path read' ela= 0 p1=202 p2=955893 p3=16

As I understand it, p1 is the file number and p2 is the block number, but my database does not have a file number 202. What am I missing here?

Thanks,
Peter Schauss
