can we install opensuse 11.4 into a folder of hard ??
 

hello
can i install opensuse 11.4 into a folder of my hard without being force to format full drive???
I mean in ubuntu cd theres an option that allows us to install it into a folder of a drive
could this be possible on opensuse???

What you are referring to in Ubuntu is called a wubi install. It basically installs Ubuntu inside your windows OS in a folder.
I don't think Opensuse has that. There is absolutely no reason you would have to format your entire drive to install Opensuse!!
You could create another partition from free space, resize a current partition or install to an existing partition. Not knowing your partition setup, it's not really possible to give specific advice.

thanks a lot
and after doing that, could it be possible to see my linux partition in widows??
and can I format my linux partition and use it for windows again or not?

You will be able to see and should also be able to write to your windows partitions from Linux by default with Opensuse.
As far as I know, you will not be able to see your Linux files in windows unless you download third party software. I googled "read linux filesystem on windows" and got a lot of hits - ext2 ifs for windows being one. I'd suggest you do a search as I'm not familiar with these programs so can't say.

Yes.
