OBB file installation on Galaxy note 8

[naungnow]

I would like to play some big game with about 100 MB obb file. But i don't know how and where to install the obb file in my note 8. According to the online manual, I noted that, to put it to sdcard>android>obb. But in my note, I found the android folder in internal storage as "emulated>0>Android>MiniSNote, data and obb", not on sdcard.
Q1. So, what shall I do?
Q2. Which one do need to be install in first, shall apk file or obb?
Q3. How to put the obb into "obb folder" for example; only .obb file or with cover folder (.com folder include .obb)

Please

Now I know the answer and I success like that;
First copy two of files apk and obb (according to folder)
And, put the obb folder into emulated>0>Android>data file (internal storage)
And installed apk and played it.
It was pretty success.
