The Parted Magic OS employs core programs of GParted and Parted to handle partitioning tasks with ease, while featuring other useful software (e.g. Partimage, TestDisk, Truecrypt, Clonezilla, G4L, SuperGrubDisk, ddrescue, etc...) and an excellent set of info to benefit the user. Parted Magic is licensed under the GPL, so an extensive collection of file system tools are also included, as Parted Magic supports the following: btrfs, exfat, ext2, ext3, ext4, fat16, fat32, hfs, hfs+, jfs, linux-swap, ntfs, reiserfs, reiser4, xfs, and zfs. Parted Magic requires at least a i686 processor and 312MB of RAM to operate or 175MB in "Live" mode.
