I WAN T TO CHANGE TO NTFS
how i change my file system to NTFS in LINUX?
is it applicable only in kernel 2.6 / Redhat linux 10 ?

You can't change the filesystem of your Linux partition to NTFS and still run Linux. That is only for WIndows systems. You could reformat a partition on your hard drive to NTFS, but not the partition you currently have Linux running on. What exactly are you trying to do?

DEAR FRIEND
pls refer kernal compilation menu there is a support to ntfs option , sso there must be a way 2 change to ntfs. dear friend plz confirm that NTFS is also applicable to linux
in suse it works very well

The kernel will support NTFS if you compile it into the kernel, as you have said there is an option for it, but it isn't considered stable at all, further more unix permissions won't work. Personally I wouldn't like to write data to an NTFS file system, reading from one almost has me biting my nails, waiting for something to go wrong

So do you mount an NTFS partition then? If so, most recent Linux distros will already have NTFS filesystem support built into the kernel, simply mount it whever you want:
assuming /dev/hda1 is your NTFS partition and you want to mount it to /mnt/windows. Sholdn't be a need to go poking around recompiling the kernel.
As phil has already mentioned though, writing back to NTFS isn't considered a good idea, but reading should be fine. I've resized NTFS partitions without problems and read data off them for a couple of years, but still wouldn't want to write large amounts of data back to it as you loose the security permissions that make NTFS worthwhile implementing over FAT32. I'm sure others will say NTFS is fine to write back to, but I wouldn't risk it.
