Note this is not the Linux btrfs:

"WinBtrfs is a Windows driver for the next-generation Linux filesystem Btrfs. A reimplementation from scratch, it contains no code from the Linux kernel, and should work on any version from Windows XP onwards. It is also included as part of the free operating system ReactOS."

This is from the ntfs2btrfs maintainer's page.

It's the same file system, with two different drivers for two different operating systems.


The metadata is adjusted for Windows in a way that is foreign to Linux.

Do Linux NTFS drivers deal with alternate streams?

"Getting and setting of Access Control Lists (ACLs), using the xattr security.NTACL"

"Alternate Data Streams (e.g. :Zone.Identifier is stored as the xattr user.Zone.Identifier)"


Not sure what point you're making here. WinBtrfs is a driver for the same btrfs filesystem that Linux uses. It's most common use case is reading the Linux partitions in Windows on machines that dual-boot both operating systems


What? Why would you need a Linux NTFS driver to read a btrfs filesystem? that makes no sense.

Storing Windows ACLs in xattrs is also pretty common (Samba does the same)


I'd delete my comment if I could at this point.


Yes it is?
