Windows Disk Manager has to be one of the most limited disk manager / partitioning tools that I've ever used, and I've come across plenty of other disk partitioning tools for Windows, but they've all been closed source.

Can anybody recommend a good, open source disk manager for Windows?

  • Did you try Paragon Partition Manager Community? You can create live disk with it.

gparted is a linux based boot disk/boot flash program that few would consider limited.

from the site:

Perform actions with partitions such as:

create or delete
resize or move
set new UUID
copy and paste

Manipulate file systems such as:

ext2 / ext3 / ext4
fat16 / fat32
hfs / hfs+
lvm2 pv
reiserfs / reiser4

I have used the program a number of times with zero problems. Perhaps the greatest nuisance is to occasionally have to disable the secure boot feature of some computers.

    Unfortunately, it seems like it has to be run from a USB drive or a CD in windows, which is extremely inconvenient for me. Commented Jan 8, 2020 at 23:28

    One consideration when performing partition edits is that a mounted drive cannot be safely modified. By booting to a DVD or USB drive, the drives in question are not mounted, facilitating the process. Good luck with your search.

  • Gparted on USB is my go-to tool for this. Great suggestion!

  • Gparted is a boot system, and works independently of the operating system installed.
