EaseUS Partition Master

Name: EaseUS Partition Master
Availability: InStock
Author: EaseUS

A disk management tool for resizing, moving, merging, and migrating partitions without losing what is on them, with a bootable WinPE build for the operations Windows will not allow on a running system.

Version 20.5.0 96.4 MB Windows 7 / 8 / 10 / 11 (64-bit) Updated 5 days ago

Overview

What this release is

Partition Master exists because the disk tools built into Windows do only half the job and refuse the rest. Resizing a system partition, moving one along the disk, merging two, or converting between partition table types are all everyday needs that the built-in tool either cannot do or will not do on the drive Windows is running from. This program does them, and does them without destroying the data in the process.

The core operations are non-destructive. A partition can be shrunk to free space, another grown into it, two adjacent ones merged, and the whole layout rearranged, all with the existing files carried through intact. The changes are queued and previewed first, then applied together, so the plan can be checked before anything touches the disk.

Migration is the feature that gets a machine onto a new drive. The whole system, including the boot configuration, can be cloned to a larger disk or an SSD, so an upgrade is a copy rather than a reinstall. Disk cloning covers the same ground for a full byte-for-byte duplicate.

The bundled WinPE build handles the operations that cannot run while Windows is using the drive. It boots the machine into the tool from external media, so the system partition itself can be resized or migrated from outside the running system.

Feature set

What you get

Resize and move

Shrink, grow, and reposition partitions with the existing files carried through intact.

Merge partitions

Combine two adjacent partitions into one without losing the contents of either.

System migration

Clone the whole system, boot configuration included, to a larger drive or an SSD.

Disk cloning

Make a full duplicate of a drive for backup or replacement.

Table conversion

Convert between MBR and GPT without wiping the disk to do it.

WinPE boot media

A bootable build for resizing or migrating the system partition from outside Windows.

Changes in this build

What changed

Faster resize on large partitions with many small files
Improved system migration reliability across different firmware types
Added support for larger disk capacities
Better handling of drives with an existing recovery partition
Fixed the clone occasionally missing hidden system partitions

Installation

How to install it

Extract the archive with real time protection disabled.
Run setup as administrator and complete the installation.
Apply the included registration step before performing any operation.
Back up important data before resizing or migrating, since power loss during an operation can still cause damage.
For system partition work, write the WinPE build to a USB stick and boot from it.

Questions

Before you start

Can it resize the drive Windows is running from?

Yes, though system partition operations complete through the WinPE build, which works from outside the running system.

Is resizing safe for my data?

The operations are non-destructive, but back up first anyway. Power loss mid-operation can still cause damage.

Does migration avoid a reinstall?

Yes. It clones the whole system including the boot configuration, so the new drive boots as the old one did.

Can it convert MBR to GPT without data loss?

Yes, in place, without wiping the disk, which the built-in Windows tool cannot do.
