NTFS (New Technology File System) is the standard file system applied by the Windows NT operating system, including its advanced versions - Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, Windows 7, Windows 8 and Windows 10. NTFS is superior to the FAT file system in performance, extendibility, and reliability; therefore, NTFS is well received as the top choice of file system for Microsoft's Windows operating systems.
Method 1: Resize NTFS Partition with Disk Management Utility
In Windows Vista or later versions like Windows 7, Windows 8, Windows 10 and Windows Server 2008, it's easy to resize NTFS partition by built-in Disk Management utility; here introduce the procedure in detail, we set Windows Vista as an example:
1. Right click on "My Computer" and select "Management", In the Computer Management then click "disk management". Disk Management shows the detail condition of all available partitions and disk drives. There is the C: and D: and free space on the Disk 0. look at this screen:
2. Right click on any partition that you wish to resize, and select either Extend (to enlarge the size) or Shrink (to reduce the size) according to your requirements.
Note: because there is an unallocated space near by the D: drive, so the "Extend Volume…" option in the right-shortcut menu is available.
3. Select the "Shrink Volume…" and will open the following windows, you can input the amount of space to shrink, remember that cannot exceed the size of available shrink space. (Attention: system partition just supports to shrink partition to one half at most.)
Please click the "Shrink" button to execute the operation. Windows Vista will reduce the size of the partition online immediately.
4. Right-click the C: partition, in the shortcut menu the Extend Volume is grayed out as follow shown. The main reason is that there is no unallocated space next to the C: partition, so you have to use other software like AOMEI Partition Assistant Standard, the helpful Windows partition manager to change the location of unallocated space and extend the C: partition.
