Thank you for prompt reply. Yes I have deleted many datasets through history panel but the history itself is exist.

So you're sure you have histories with deleted datasets older than 0 days? The commands you have run will not remove datasets that haven't been deleted first by a user (usually through the history panel). -Dannon On Wed, Apr 23, 2014 at 9:21 AM, Milad Bastami <mi.bastami@live.com> wrote: Dear all,I have some unwanted datasets to remove but I need their main histories, so in galaxy I just deleted the unwanted datasets but not the histories.
