I downloaded the zip-package for Factorio version 0.17.69 (https://factorio.com/get-download/0.17. ... n64-manual).
I wasn't able to extract "logistic-robot.png" at "Factorio_0.17.69/data/base/graphics/entity/logistic-robot/logistic-robot.png". (Note: this is not "Factorio_0.17.69\data\base\graphics\icons\logistic-robot.png", which i was able to extract.)
I used the standard windows explorer zip-extraction. The error code was "0x80004005" (Unknown Error).

When trying to extract with WinRAR I get a more helpful error message, which states that there is an error with the Checksum and that the archive is damaged.

I already downloaded it again, after it didn't work so the problem probably doesn't happen when downloading.

What is the file size of Factorio_x64_0.17.69.zip?

Size: 1,22 GB (1.321.114.304 Byte)
Size on disk: 1,22 GB (1.321.115.648 Byte)

I'm not sure what exactly the difference between these two is.


I downloaded Factorio_0.16.51 and i was able to extract the logistic-robot.png from there. It has the same CRC-32 checksum (?) and size, so I think it is the same picture. I'm not sure, if the CRC-32 value would change if the archive is damaged.

The difference with size and size on disk is how the system manages 'allocation units', which are the smallest piece of disk space addressable. For a long time, the smallest allocation unit would be 4 kilobytes, so a 1 kilobyte file would require 4 kilobytes of disk space, or a 499 kilobyte file would require 500, the nearest multiple up.

ah, interesting
thanks
