Resizing a NTFS Patition

I have WIN XP on a 30G hardrive formatted in the NTFS file system. I have about 20G free and would like to install RH Linux in part of the free space I have. I need to resize my NTFS partition to make room for a Linux ext3 partition. I have downloaded a few partition manipulation programs that only work with FAT 16 & 32. I have looked at Partition Magic, but don’t know if it will resize an NTFS partition.

Is it possible to resize an NTFS partition? I have consulted a couple computer books I have an cannot find a clear answer. If it is possible, any recommendation on software would be appreciated.

Thanks!
