Are there any elegant file manager for linux

Tweet

I am using Ubuntu 12.10.Few years back i have seen nautilus file browser with nautilus clutter flow or something ,Gloobus clutter flow,like elegant file browser.But i try to find out how to install them to my computer.But i couldn't find them.It looks that they are no longer available.But it is unlikely.There should be better software than which was available few years back.Where can i find them.How can i install them.
