Windows Explorer can show a folder's (recursive) size by opening its Properties. Calculating the information usually takes a while, especially on non-local disks like attached USB devices (my phone). When I see the size or count increase, I know Explorer is still calculating. But sometimes it takes many seconds before it increases any of those figures.
How do I know when Windows Explorer is done calculating the folder's Properties?
The same applies to multiple selected files or folders.
I'm using Windows 7 specifically, but would like to know for other versions as well.
