mount directory part to new partition

[Nikos Voutsinas]

Hello,   Besides tar cvf.....tar xvf Is there any other way to move a directory part to newly created partition? e.g. I want the /usr (became too big) to move it in a new partition and after this to mount /usr to this partition?   ps The problem is that thereis no space left in the current partition (Available 0%), so I suppose that I should use something to dump /usr into /dev/newpartition   Thanks
