Why is my savefile still so large?

[Zaflis]

Steps i've done:
- Deconstruct everything, including all concrete.
- Use console command to delete all items on ground, such as alien artifacts.
- Use console command to clear all pollution.
- Use console command to kill all aliens.
- Use undecorator mod.
- Tried loading the game without mods and saving, it is still same size.

The area i have explored is a bit large circle around spawn. After all these things the level.dat is still over 93Mb uncompressed. Is there anything that can be done to reduce that file size?

Because you explored the map.

That's not exploration, i was only about to start actually exploring What is there to take so much data for empty tiles?

Lets see what fills so much in that save file.

The original file was 91.2MB.
Saving the file with no mods reduced the file size to 90.3MB

I then ran the following command to delete all entities

Code: Select all

/c for _, ent in pairs(game.surfaces.nauvis.find_entities()) do
	ent.destroy()
end

After that the save file was 51.8MB.
Now the map consists of 51319 chunks and each chunk has 32 * 32 = 1024 tiles in it so the map is made out of 52550656 tiles.
Dividing the size of the save file with the number of tiles and we get 1.03376. From that we can assume that one tile takes 1 byte of space. Then we can remove all the tile bytes and we get 1774221 bytes for everything else.


tldr:
Mods: 0.9MB
Entities: 39.4MB
Tiles: 50.1MB
Other: 1.7MB
