is it normal that the file doesnt have extension?

Yes. I plan to change that in the future because this is confusing a lot of people. But for now the files don't have an extension.

@tobilinz i have put the file in the folder but they dont show up (the aasm)

1. Go into your .minecraft folder
2. Create a new folder named autokey
3. Go into that autokey folder
4. Create a new folder named Cane farm builder inside the autokey folder
5. Put the file inside that folder

oh
