Repartition Drives without loosing your data

During installing of windows we can create only 4 partitions(drive,volume), but if we want to create more than 4 partitions or want to create a separate drive for purticular data, we just bother about our important data because there is a chance to loose our important data, and previously versions of windows(xp) dont allow us to create new partition or drive without deleting that drive.
again taking backup and creating new partition its wastage of our specious time. But new versions of windows like windows7, windows vista have a magic option called as "shrink volume".
with this option we can create new partition without disturbing that drive, how much free space available in that drive can be use for new drive. and if there is free (unallocated) space in your hard drive so it can be add with any drive by using another magic option called "Extend volume".

and taking benefit from this options you need not to ask or call any engineer, you can do it by yourself it is very easy,
Dont depend on others be your own master...
