compiler path

When compiling messages shows a path for other output files:

C:\Users\pc\AppData\Local\Temp\Arduino_build981235

Can't find it (Win7), how to access?

They where hidden, but found it.
.cpp and .elf files seem not readable
What is the extension of a readable asm file?

See reply #2 in your other thread.

Relply #11 in https://forum.arduino.cc/?topic=424340#msg2927534 gives an example. I've seen a lot more examples, just search this forum for avr-objdump
