When I run this scetch, I get this error:

In function ‘void playcomplete(char*)’:
error: ‘playfile’ was not declared in this scope

What is wrong?

(I assume it's technically possible, but I mean do the the current libraries easily support that.) Can it play backwards too?

But I'll bet its confusing to some of other Arduino users, who, like myself, aren't adept C programmers and have only studied the Arduino programming reference (and your excellent tutorials, of course).

"int" varies on platforms, from 2 to 4 bytes, which makes code less portable. if you say uint32_t then there is no confusion! :) they are completely identical. i use uint8_t, etc because that way it is extraordinarily clear what type it is. “int” varies on platforms, from 2 to 4 bytes, which makes code less portable. if you say uint32_t then there is no confusion! :)

I gather that they are integer data types and that u indicates unsigned and the digits 8,16,32 represent the number of bits. But how are they different from byte,int, unsigned int, long and unsigned long? I’m a bit confused about int16_t and uint32_t.
