Compile general infomation

perhaps this question has been asked...or i simply haven't looked hard enough to find the answer...either way...i'm just curious...

when unity compiles my projects...it seems to be all compiled into one .exe file...i may just not be seeing any other files...or is this what unity does?

if this is how unity works then how would i do an update for a game after i change things?

this part is still completely unclear to me...i'm just wondering if someone could please clarify this subject for me...

thank you for your time...

To "update" a game you would just build it again after you've made changes.

When you build a project, Unity creates an exe file and data folder (or other filetypes for other platforms) with all of the information needed to play the game.
