10 Best Free Disk Partition Software Tools

MiniTool Partition Wizard includes more partition management tools than most similar programs, even ones you might pay for.

Not only does the free MiniTool Partition Wizard support regular functions like formatting, deleting, moving, resizing, splitting, merging, and copying partitions, but it also can check the file system for errors, run a surface test, wipe partitions with various data sanitization methods, and align partitions.

In addition to the above, MiniTool Partition Wizard is able to move the operating system to a different hard drive as well as recover lost or deleted partitions. There's also a file recovery program, disk space analyzer, and benchmark tool built in.

One thing I don't like about MiniTool Partition Wizard is that it doesn't support manipulating dynamic disks.

Windows 10, 8, 7, Vista, and XP are the supported operating systems.

AOMEI Partition Assistant Standard Edition has a lot more options that are out in the open (as well as hidden away in menus) than many other free partition software tools, but doesn't let that scare you away.

You can resize, merge, create, format, align, split, and recover partitions with AOMEI Partition Assistant, as well as copy whole disks and partitions.

Some of the partition management features with AOMEI's tool are limited and offered only in their paid, professional version. One such feature is the ability to convert between primary and logical partitions.

You can also use AOMEI Partition Assistant to create a bootable Windows flash drive, move an operating system to an entirely different hard drive, and wipe all the data from a partition or drive.

This program can be used in Windows 10, 8, 7, Vista, and XP.

Active@ Partition Manager can create new partitions out of unallocated space as well as manage existing partitions, like resizing and formatting them. Simple wizards make it easy to walk through some of these tasks.

No matter what kind of file system you're using, the free Active@ Partition Manager tool should be able to handle it, with support for all the common ones, like FAT, NTFS, HFS+, and EXT2/3/4.

Active@ Partition Manager includes other features, too, like imaging a whole drive for backup purposes, converting between MBR and GPT, creating FAT32 partitions as large as 1 TB, editing boot records, and rolling back changes by auto-backing up partition layouts.

When Active@ Partition Manager resizes a partition, you can define the custom size in either megabytes or sectors.

Unfortunately, Active@ Partition Manager can't resize locked volumes, which means it won't let you change the size of the system volume.

Active@ Partition Manager should work just fine with Windows 10, 8, 7, Vista, and XP, as well as Windows Server 2012, 2008, and 2003. 

Managing the size of a partition in EaseUS Partition Master is dead simple thanks to their easy to use slider that lets you drag left and right to shrink or expand a partition.

Changes you apply to a partition in EaseUS Partition Master aren't actually applied in real time. Modifications exist only virtually, which means you're only seeing a preview of what will happen if you save the changes, but nothing is actually set in stone yet. Changes don't take effect until you click the Execute button.

I particularly like this feature so things like expanding and copying partitions can be done in one swipe instead of having to reboot between each operation, thus saving tons of time. The list of pending operations is even shown on the side of the program so you can clearly see what will happen when you apply them.

You can also password protect EaseUS Partition Master, hide partitions, upgrade the system drive to a larger bootable drive, merge partitions, defragment a drive, and copy Windows to a different hard drive.

One thing I don't like about this program is that several features are only available in the full, paid version, but are still clickable. This means you might sometimes try to open something in the free version only to be prompted to buy the professional one.

EaseUS Partition Master works with Windows 10, back through Windows XP.

GParted runs entirely from a bootable disc or USB device, but it still has a full user interface like a regular program, so it's not at all difficult to use.

Editing a partition's size is easy because you can choose the exact size of the free space before and after the partition, using either a regular text box or a sliding bar to visually see the size increase or decrease.

A partition can be formatted in any one of several different file system formats, some of which include EXT2/3/4, NTFS, FAT16/32, and XFS.

Changes GParted makes to disks are queued up and then applied with one click. Because it runs outside the operating system, pending changes don't require a reboot, which means you can get things done that much quicker.

A small but particularly annoying issue with GParted is that it doesn't list all the available partitions on one screen like most other free disk partitioning programs. You have to open each disk separately from a drop down menu, which is actually easy to miss if you're not sure where to look.

GParted is over 300 MB, which is much larger than most of the other programs on our list, so it may take some time to download.

Like GParted, Cute Partition Manager doesn't run from within the OS. Instead, you must install it to a bootable device like a disc or a flash drive. This means you can use it even if you don't have an operating system installed at all.

Cute Partition Manager can be used to change the file system of a disk and create or delete partitions. Any changes you make are queued up and can be undone because they are only applied when you save them.

Cute Partition Manager is completely text-based. This means you can't use your mouse to select the different options — it's all done with the keyboard. Don't let this scare you off, though; there aren't that many menus and so it's not really a problem.

I love Macrorit Partition Expert's user interface because it's super clean and uncluttered, making it very easy to use. All the available operations are listed out on the side, and none of them are hidden away in menus.

Some of the actions you can perform to a disk with Macrorit Partition Expert include resize, move, delete, copy, format, and wipe a volume, as well as change the volume's label, convert between a primary and logical volume, and run a surface test.

Like most of the partition management software in this list, Macrorit Partition Expert doesn't actually make any changes to the partitions until you apply them with the Commit button.

One thing I don't like about Macrorit Partition Expert is that it doesn't support dynamic disks.

A portable version is also available from the Macrorit website.

If walking through wizards helps you feel more comfortable making changes to partitions, then you'll like Paragon Partition Manager Free.

Whether you're creating a new partition or resizing, deleting, or formatting an existing one, this program has you move through a step by step process to do it.

Paragon Partition Manager Free supports common file systems like NTFS, FAT32, and HFS.

Unfortunately, a number of additional features are disabled in Paragon Partition Manager, available only in the pro version.

IM-Magic Partition Resizer works very much like the tools mentioned above. It installs quickly and is super simple to use.

With this tool, you can move partitions, resize partitions (even the active one), copy partitions, as well as change the drive letter and label, check the partition for errors, delete and format partitions (even with a custom cluster size), convert NTFS to FAT32, hide partitions, and wipe all that data off of partitions.

All of those actions are extremely easy to find because you just have to right-click the device you want to manipulate. As you perform these actions, you'll see the program update in real time to reflect them so that you can see how it will look when everything has been applied.

Then, when you're happy with the results, just hit the big Apply Changes button to put everything into action. If you have to reboot for anything to take effect, IM-Magic Partition Resizer will tell you so.

You can also view the properties of any drive, to see its NT object name, GUID, file system, sector size, cluster size, partition number, physical sector number, total number of hidden sectors, and more.

The only downfall I can see with this program is that a few of the features require that you upgrade to a paid edition. For example, you can't make the bootable media program that they support unless you pay for it.
