Adjust partition size is to extend or shrink partition. Usually, you need to change a partition size under the following two conditions:
In Windows Disk Management, you can use its Extend Volume or Shrink Volume Wizard to adjust partition size, just like the following screenshots.
Note: To extend a partition via Disk Management, there should be a contiguous unallocated space behind the partition that you want to extend.
But in many cases, there is no adjacent unallocated space behind the partition that you want to extend and you can't get such a space through shrinking partition. After you shrink the partition behind C drive (here is E drive), the unallocated space is behind E drive. Right-click C drive and you'll find that the Extend Volume greyed out.
Thus, here we introduce an easy-to-use partition manager, Qiling Disk Master Standard, an easy-to-use and powerful partition manager for Windows 10/8.1/8/7, XP, and Vista.
