This is pretty old question but I don't know why my all friends answer that there is no such command. Here is the command:
dir /o:s
I saw comments that its not working on folders, for the same reason I am editing my answer. This command supports folders too.
I ran this command on my local machine in one folder and below is output
d:\Moody>dir /o:s
Volume in drive D is Data
Volume Serial Number is CE51-A3E6
Directory of d:\Moody

Apart from files which are showing sizes my folders are arranged too. When I check size of binding; its nearly 18 KB; and last folder repository is nearly 1 GB. So it works on folder too.
