With –binary option I get size of 174Mi in eza. Experimenting with some other options didn’t help. If something is ignored (maybe gitignore), then it would be that du AND Dolphin filemanager would ignore those files, and eza would not. Which its hard to believe for me. I also deleted the .gitignore and .git files/folder to see if it makes any difference and no, it did not.
The only thing I can think of is maybe something going on with link files, but no idea how or what to test for here.
