GParted is a GTK+ frontend to GNU Parted and the official GNOME Partition Editor application. It is used for creating, deleting, resizing, moving, checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks and mirroring one partition with another (disk imaging). GParted is developed on GNU/Linux.
- GParted is one of, if not the best alternative to EASE US if you are using a GNU/GNOME Linux distro like Ubuntu. If it's available for Windows, I've never tried GParted on a Win OS before, so I couldn't vouch for that either way. It's excellent when used on Ubuntu though!
- GParted is not only free but open source, which automatically indicates higher-than-average quality (in my experience). Also, it has every feature Easeus Partition Manager has, and although it's technically a Linux program, as a live CD it can operate on nearly any platform's HDD or SSD. Highly recommended.
- Needs to be booted from Linux, but can otherwise manipulate most filesystems, FAT16, FAT32, NTFS and with some limitations, HFS, HFS+, even exFAT. Of course, ext2, ext3, ext4, and Btrfs. As long as you can run it from a minimal Linux (or BSD?) like GParted Live on the website, it can manipulate partitions, much more than Partition Master.
