It's not a folder with 100,000 files it's a .grfActually theres only 9,021 Files in the data folder.hmmm... that's weird. It shows up as 100,000 files when I'm deleting.
Well, it takes longer to process 9,021 files than 1 file.
The main reason I left it as a data folder is because it gives people a chance to edit it and turn it into their own GRF when and if they want to instead of having them download a pre-made GRF and then they have to extract the GRF, edit, and recompileWell, the unpacked and packed versions are up there... This pre-made grf just makes things easier.
