File Extension, I Know Its Not An .exe

I'm downloading a file from kazza with the file name:

Quark-Xpress-Multilang-Final.EXE

its supposed to be a mac program and i'm pretty sure that the file isn't an exe anyway that they just did that so the serach could find it better, but, anyone have an idea what i should change the file to?

.sit ?

we'll see, its gonna be done it about 5 mins , meaning 20 im sure, but what other types are there, does bin work on mac too?

oh and how do i burn an image file with a bin without a cue, nero looks for cues not bins, or should i just burn as data?

i changed it to .sit and when i put it on the mac it said this doesnt appear to be compressed or incoded etc.. the same thing when i burned it as a .bin but only as a data bin not like a real image because i'm still unsure how to do that. Any other suggestions?
