You can tell Finder to show actual folder sizes instead of just "--". Right click in a folder -> Show View Options -> Calculate all sizes. I'm not sure why it's not the default, it's not like Finder needs to traverse the folders hierarchy to calculate the size (I hope!).
- tgv 6y agoIt does traverse the folders to do just that; look at your CPU usage with that option on.
- oneplane 6y agoIt does have to traverse the complete filesystem to calculate the sizes. That is how most filesystems work (files have sizes, folders do not - so a folder size doesn't exist and is just a sum of whatever it contains)
- jiripospisil 6y agoInteresting, I thought it uses the Spotlight index to get this information and that the index already contains these aggregates, but you're probably right considering that it works even in folders that I've explicitly excluded (I wonder how many millions of node_modules folders are indexed for no reason).
