Normally in computer we do the partition of the hard disk before install the operating system, however some people when they install the OS at the first time they wouldn’t do the partition of hard disk, or they forget. They only have C: drive in the hard disk. It is not a problem; however They cannot properly handle the files. So it’s better partition the hard disk as several separate parts. For this purpose there are few ways in the OS.
But the facilities on that ways are very less. There are many soft wares in the web to do partition and to make changes on the hard disk which already finished the partition “Aomei Dynamic Disk Manager” Is one of that.
Download this software and install in ur PC then you can manipulate the hard disk as what you want. This is a beta version. We can make changes on the hard disk which already finished the partition. This beta version is only until July 31, the whole version will be come up in August.
