Hard disk drive is an indispensable component in Windows computer, no matter you use SSD, mechanical disk, or any types of RAID array. Before saving files to a brand new disk, you should initialize it, create partitions and format with a file system. After running the computer for a period of time, you need to shrink, extend, convert, copy disk partitions, etc. A reliable disk partition tool can help you accomplish these tasks. To manage disk partitions in Windows desktop/laptop/tablet, there's a native free partition manager - Disk Management. It is able to do some basic management operations such as create, delete, format partition and change drive letter.

From Windows 7, new Shrink and Extend Volume functions are added in Disk Management. But the Shrink Volume function can only shrink NTFS partition to create new. Extend Volume function can only extend NTFS partition by deleting the contiguous volume on the right. To manage disk partitions in Windows, third party software is better choice. This article introduces the best free partition software for Windows 11, 10, 8, 7, Vista, XP (32 & 64 bit).
