Fstransform is a change tool in file system format. It is characterized by working locally without backup. For example, it can change JFS, XFS to Ext2, ext3, or EXT4 formats. The current version is only Linux tested, it takes a sparse file to create a new file system image, goes into all the files on the existing file system, and then maps back to the original partition sparse file.
Fstransform 0.9.3 This version strengthens the "Fsremap", increasing the functionality of automatic checkpoints and recovering unfinished work. Enhanced "fstransform", the ability to add non-installation devices, transform errors, insert appropriate cleanup, and add new options to ease integration with third-party tools (such as gparted). Some of the options have been slightly renamed, and persistent files and logs are stored in/var/tmp/fstransform/.
