Question about extracting map files for a 2d game made of Unity

[hamburger1234]

I want to extract data from a video game. The game is made with Unity 2D Maker, and the game's files are saved in the _data(846KB) & _info(1KB) format.
Most of the information, including the texture, seems to be saved in the _data file, I guess.

Textures such as maps and characters could be extracted through Asset Studio.
But, I couldn't extract data files which allows me to bring the character to Unity. Literally, I can only extract textures, not imformation.

I could open the file in Hexeditor, but as you can see in the picture.
I have no idea exept the file is UnityFS something like that. Can I do something with them? What is UnityFS?
And the map texture is broken down into several pieces, and I guess it is because it is a tile map.

I will share the files with you through Google Drive.

What I want to ask as a whole is,
can I open the 2D map file in perfect condition, not in pieces?
And is there any other way to bring them up to Unity? (including player characters)

The game name is Zombie Highschool(좀비고등학교)(殭屍學園)
