Difference between gateay export and designer export size?

I have a project I am pushing changes to production later today. I exported the project in full from our development system in Designer and from the gateway. I noticed the one from the gateway was 1kb more (in zipped format) than the one from designer.

I unzipped them and they both have the same number of files 382, and folders 190, but the one from designer is 6,225,609 bytes and the one from the gateway is 6,228,646. I've never had a problem doing a push with either method on this system and I don't expect one today, but I am curious - what is with the extra 3,047 bytes from the gateway export vs the designer export all method here?

I assume I am forgetting something basic that was gone over in IA University, or that it's a nothing burger, but still curious about it.

Don't think there's any actual difference. I think its a windows thing? I inspected the page-config folder in both and for some reason the one exported from designer had the size on disk 0 bytes for both files, while the resource.json file had 8.0kb for the "size on disk" for the gateway export, but inspecting the actual contents revealed they were identical albeit it the json in slightly different order. So I am not worried about it at all.
