How does OpenStreetMap store it's map data?

I'm woking in AutoCAD at work and I'm getting the feeling that if I were to store the OSM map data in AutoCAD it would be a huge file, yet the files I download in CoMaps are small with regards of how much data they contain.

@spacebug I mean, you probably don't need all the data right? just a section of it?
Any idea what file format you want?

I think a lot of people use Qgis for this

https://wiki.openstreetmap.org/wiki/Converting_map_data_between_formats
shows several tools, including qgis to do this.

So you choose your area in qgis, then export to xdf

@spacebug I think you can also for example download an entire country or region of a country by downloading the pbf file from here:
https://download.geofabrik.de/
And then using something like this

to then convert it to autocad
