What i did is kept the TEMP window open while i was compiling and flashing the program into the ATmega using the Arduino IDE ,then i saw all the file coming with the specific button's i did clicked on the IDE , also i saw an assembler file being manufactured and suddenly going out and then a folder placed with various C++,O,HEX format file(which had one C++,HEX file), but every file had a cpp added to it so the HEX file was like xyz.cpp.hex so it means it is the hex of c++ file,i think but dn;t know where is the 6KB file.
