linux – What kind of files are these? Compiled files, self extracting files or something else?

I’m a newbie using linux. I understand that there are binary packages a source code that may come in .zip. However I downloaded a zip package (you can see in the picture). I just extracted, then cd into bin an run “autopsy”.

Is this a self extracting file? Is this a compiled file? Are self extracting files, compiled files? I used “extract to” to extract the file no other software was used, this make the file self extractable?
