Well, I give you examples of OS belongs to a file: If a file is .exe, it means that it's for Windows, If a file is .apk, it means that it's for Android. What OS belong your file, Windows, Mac, iOS, Linux or Android?
it is an asm file
.asm is not a OS file, is a language assembly file, but it can be opened in Vim, Notepad, .etc
well I used it to make an OS......
