Hi,
I need to free space in rootfs partition, I know that is a system partition but how to know what directory or file delete?
In other words I need to know what directory or file are using more space.

Thank you.

Why do you need more space? Your root partition is already huge and it
has as much space left as some people’s entire root partition!

du -sh is your friend.
Just like that it will tell you how much space is used in the partition
(if you run it from the directory at the top of the tree)
If you run ‘du -sh ’ it will tell you how much each top-level directory
uses. Then if say /etc is using more than you expect you run 'du -sh
/etc/’ to find the next level directory and repeat until you find the
source of your problem.
This is mine:

Which confirms what djh-novell says: My / usage is smaller then what is free in yours.
I think you first have to explain why yours grow so big before we can give you any advice on what to remove.
And yes, when you do not even know what you have put there, use the method described above,

Other tools: I use midnight commander, it also measures directory sizes
(C-space, command menu). Or if you like GUIs, ‘baobab’ is very good for
this purpose. Or kdirstat if it is still distributed, or filelight.

Most database mangers default to using root to store there databases also setting up a large web site with defaults will use space out of root. Of course it is better practace to set up separate partitions for these programs to use. Makes upgrading and backup much much easier.
