I tried to create a bin in the "Sketch -> Export Compiled Binary" menu and 3 files appeared with the extension Blink.ino.bin, Blink.ino.elf and Blink.ino.map.
is this a problem?
and I want to re-upload to another esp8266 with flash_download_tool_3.9.7.exe and then it doesn't work.
is there any help with the tutorial until it's finished?
No; or at least not for AVR based boards (not familiar with the process for the ESP8266).
It doesn't work is quite useless; please provide details like wiring (if it is not USB), the command that you issued and the full error message. Those that have knowledge of what you're trying to achieve might need that information.
Did you base your command on the verbose output of the IDE?
Your topic has been moved; you're using IDE 2.x and have an upload problem but posted in IDE 1.x.
@sonofcy, with some bad luck the IDE will take 10 minutes to compile again. It might also be that OP just wants to send it to somebody else with instructions how to upload.
Plenty of reasons why one might want to upload without the full IDE being involved.
