Downloading maps question (sh.itjust.works)

I have 1 TB of storage on my phone, sometimes it's more than I know what to do with.

So I downloaded every map available in CoMaps. Every. Single. Country.

The result is about 92.1 GB of storage being taken up, for those who are curious

The thing is though, every time a new map update comes out, CoMaps makes me re-download all 92.1 GB of my downloaded maps all over again.

For example, let's say a new map update comes out, and instead of being 92.1 GB, it is now 92.2 GB. Even though there was such a small increase, all my maps from Afghanistan to Zimbabwe and everything in between have to be re-downloaded.

Not only is it annoying for me, but I feel like it strains CoMaps's servers when I tell it to download almost 100 GB of map data every week or two and I feel bad for it

So basically, when there's an update for some of your maps, it won't just grab the new information, it will also re-download all the old information it already had before it seems. Not sure if this is a bug or a feature with a valid reason for being implemented

Has anyone else noticed this or experienced this?

Yeah, CoMap maps don't have diff updates. That's not something they can easily implement, it would take a lot of hard work.

So you can either update everything as you have been doing, or stay on the previous version (and only update the regions you're actually using).

I couldn't tell you how significant the 100 GB is on the servers, it might be a drop in the ocean, or it might not.
