Move only folders and skipping files

How do I move all folders and its contents from a directory A to another directory B, skipping all files in Directory A ?

Ok. Got it.

mv /A/*/ /B/ 

The * globbing cannot distinguish between files and directories.
You need another step.
Here the directories are collected in a sub command:

mv $(find /A/* -prune -type d) /B/

Oh yes, the /A/*/ trick works, too!
