To use disk space more efficiently you’d better create more than one volume especially when you have a large hard drive. Separate partition for system, programs and personal files. It is a good way to organize files and improve computer performance. However, there is still an issue of disk space usage especially for system C drive, which is very likely getting full. It cannot be better if you can resize Windows 7 partition drives, otherwise, you have to start from scratch to reinstall Windows and programs.

In Windows 7, partition resizing become much easier than previous Windows XP, because Microsoft added new Shrink Volume and Extend Volume functionalities in Windows 7 Disk Management console. However, not all disk partitions can be resized due to some inherent limitations. In this article I’ll show you how to resize partition in Windows 7 (32 bit and 64 bit) with built-in Disk Management and professional disk partition software.

Resize partition with Windows 7 Disk Management

If your disk partition configuration fits for the requirements, you can change partition size in Windows 7 Disk Management without third party partitioning software. Windows 7 DM is easy to resize partition, working fast, but as I said above, some partitions cannot be shrank or extended.

How to decrease size of a partition

  2. Right click C drive and click Shrink Volume.
  3. Enter the amount of space and click Shrink to execute.

Type space

Limitations of Shrink Volume functionality:

  • Only NTFS partition is support, FAT32 and other types of partitions cannot be shrank.
  • Unallocated space can only be generated on the right side, so you cannot extend other drive with this free space.
  • You cannot shrink volume beyond the point where any unmovable files are located, that means you can only shrink little space.

How to increase partition size

Note: only when there is adjacent Unallocated space on the right side, you can expand a drive with Extend Volume, otherwise, Extend Volume is grayed out, steps:

  1. Open Disk Management
  2. Right click the drive that has adjacent Unallocated space and select Extend Volume.
  3. Extend Volume Wizard will be opened, simply click Next to finish..

Limitations of Extend Volume:

  • Only NTFS partition is support.
  • Extend Volume only works when there is adjacent Unallocated space on the right side.
  • Free space of Logical partition cannot be extended to Primary partition even if this space is right adjacent, and vice versa.

To resize Windows 7 volume drives, 3rd-party partition software is better choice.
