Looks great. Did we want to go through the trouble of compute the size of subfolders? Right now it just the cded but in the output of show_cached_files the CDED directory has a size zero.

I wondered about that too... or an argument (or other function) to show the cded cache?

Feels like it belong in the show files function somehow especially since it is likely to be by far the biggest thing taking up space. I guess you could have show_cded_cached_files and then have show_cached_files call that?

I guess just expanding the cded folder would be the simplest... with a cded (logical) argument whether or not you want to show it?

I think that might end up being less useful as 95% of the files are cded files. I wonder if we could summarise it by the directors or files at this location: bcmaps:::data_dir()? So in this case cded is just the sum of file sizes of a recursive list of what is in cded.

Yeah that's good

Ok, I think this works now. Lists the cded dir (or any dir, but right now that should be the only one) with the sum of the files. I also modified delete_cache() so that the cded dir is also deleted (when specified or when files_to_delete = NULL).
