I am not personally interested. I am just saying that I see no reason to go posting executable files hidden with passwords. Just post the datasheet and stop the nonsense.
I assume you are referring to the password'ed zip I uploaded. The zip contains much more than just the Chinese datasheet, it contains code, and at least one Windows executable which is used... in some manner.... to .... do something .... to the device in question (JQ8400 MP3 Players), I think basically some sort of configuration or programming tool for the microcontroller built into the thing.
I don't think it's nonsense to make that available in case somebody wants it, and the only way to do it is to password the zip so Chrome etc won't forbid you from getting it.
But anyway, here is the datasheet on it's own
JQ8400_Chinese.pdf it has a screenshot of what I assume is the executable in the zip on the last page.
