This feature is reserved for about 8 years. But it never worked reliable.
Google for the story. I wrote above the keyword (e2compr).
> In what way are the compression features in NTFS different?
It works reliable since about 8 years. Something what none of the main
Linux filesystem can do today (ext3, reiserfs, JFS, XFS).
