Paragon ExtFS for Windows 4 has been released! Extended Ext4 Linux File System Support, Higher Transfer Rate

We have finally released Paragon ExtFS for Windows 4 – an updated version of the utility software designed to grant full read and write access to Linux file systems under Windows. Paragon ExtFS for Windows simplifies data sharing, providing users with the ability to transfer files between otherwise incompatible systems at a higher data transfer rate than native file-system performance.

New features:

  • New! Supports nearly all of the latest Linux format Ext4: 64bit, dir_index, extent, extra_isize, ext_attr, flex_bg, has_journal etc. (Linux bigalloc, journal_dev, meta_bg features are not currently supported.)
  • New! The driver now works much faster, even when the Linux volume is short on free space. The product is able to transfer a larger amount of smaller files at twice the speed, with an increased rate of random read/write operations.
  • New! Unlimited trial version. Following the initial 10-day trial, the data transfer rate decreases to 5Mb/s, but the product otherwise remains fully functional.
  • New! For Windows users with less-frequent needs, the data transfer speed can be reset for up to 25 days free of charge by sharing with friends on Facebook via the in-app link.

The new version of Paragon ExtFs for Windows comes with extended support for Ext4 file formats, enabling the highest transfer speeds. The new ExtFS for Windows 4 mounts Linux volumes, including those over 2TB in size, up to two times faster than the previous version. Best of all, for owners of Paragon ExtFS for Windows Professional 3, the upgrade is free.

Paragon Hard Disk Manager for Mac

    • The new ExtFS for Windows mounts Linux volumes much faster, including large volumes over 2TB;
    • Ability to mount any number of Ext 2/3/4 partitions at once;
      • With ExtFS for Windows, the Linux logical volume manager retains all functionality, performing open, close, read, and write operations in the usual way!

ReFS Support added to Paragon Universal File System Drivers

Resilient File System (ReFS) was first introduced by Microsoft Corporation in the release of Microsoft Server 2012. Since then support of this file system has been integrated into Microsoft server and desktop operating systems like Windows 8/8.1, Windows 10, Server 2016 (Technical Preview).

ReFS was designed with one key goal in mind – file system integrity and the ability to verify and auto-correct data without need to run a separate file system checking utility.

To provide better NTFS file system compatibility for existing applications, Microsoft is using the same API for implementing file system semantics: “This code implements the file system interface (read, write, open, close, change notification, etc.), maintains in-memory file and volume state, enforces security, and maintains memory caching and synchronization for file data. This reuse ensures a high degree of compatibility with the features of NTFS that we’re carrying forward”.

Unfortunately even with the upper-layer engine nearly identical to what’s found in NTFS, up until now, only Microsoft platforms provided access to ReFS volumes; as a result, a Windows PC or a virtual machine running a supported Windows operating system would still be required to open files on Refs volumes from other platforms such as Linux, Mac, etc.

Paragon Software’s development team has been working on integrating ReFS file system support into our UFSD (Universal File System Driver) technology since 2012. We are happy to announce the present result of this work and release a Paragon UFSD driver that supports working with Refs volumes in read-only mode (full solution with both read and write support is under active development).

Introduction to the Paragon ReFS Universal File System Driver

1. Create a ReFS volume on Windows Server 2012 platform:

2. Mount a ReFS volume on Linux:

3. Copy data from ReFS on Linux:

As you can see, with the help of the Paragon ReFS driver anyone can make a copy of their data from the ReFS volume on a Linux platform, without need for a Windows PC.

ReFS Compatibility within the Microsoft Ecosystem

With the release of Microsoft Server 2016 Technical Preview versions, Microsoft has shown that it continues to develop the ReFS file system. The newest ReFS version implemented into the Server 2016 Technical Preview 5 revision is not currently compatible with the previous Microsoft platforms, like Windows Server 2012 R2.
