Hope will get answere, i want to delete all folder & sub folder including files in aix system, could you pls share the command .
AIX is not Linux. It is IBM's proprietary variant of UNIX.
( See: http://en.wikipedia.org/wiki/IBM_AIX )
Thus your question is outside the scope of this forum.
You would serve yourself so much better if you either chose an AIX forum, or perhaps reviewed the man pages in your system's environment for rm , or even thought to do a bit of research with Google searches.
