I think it is indexing/caching/something that requires it to look at
every single file in there plus all the levels below it.  If so, that
would be a huge task. Here is some info on that but I did post it a bit
ago.  It was sort of nested in one of the posts. 

23.5 GiB 154,090 files, 8,567 sub-folders

Some NASA pics can get large at times. Some I have are quite small.
Still, it's a LOT of files.
