Hello everyone, today I bring you a fresh new FATXplorer update. The update is live at the time of this post and you may download it from the downloads section or using FATXplorer’s updater. The purpose of this update is to bring further stability to the previous version and to address various issues reported by customers.

You will need to re-enter your serial number in this new version. Sorry for the inconvenience, but this is to address a compatibility issue. If you lost it, feel free to ask for it.


  • Fixed a bug that could cause progress percentages to go into the negatives when extracting/adding large content items in the Content View.
  • Fixed USB formatting bugs that could cause select USB devices to appear “Unformatted” on the Xbox 360 console. There may still be some cases of this problem, please report it if it happens to you so it can be investigated.
  • Fixed a bug that caused FATXplorer to not recognize XDK HDDs formatted with recoveries that have a QFE of 0.
  • Fixed a device renaming bug in the Device Information tool in the Toolkit View.
  • Fixed a bug that would cause an error message in various places if deleted items had a certain file name, such as browse.dat..
  • Fixed a bug where the Content View failed to add files that have the Read-Only attribute set. You no longer have to remove the Read-Only attribute on content items you want to add.
  • Some people may have been asked to downgrade the Windows integration driver only to find out that the downgrade procedure doesn’t actually work. This was an incorrect design and should no longer occur.


  • DashLaunch USB patches have been phased out in favor of a new xeBuild patch system. You can now build pre-patched nand images. This is better than DashLaunch patching because you don’t have to worry about the kxam.patch file, and you can have USBs connected on boot! The new patch system has been well-tested, is easier to use, and just works better. The Console USB Patcher has been revamped to utilize this new patch format.
  • Device detection has been improved.
  • Improved flexibility of the USB formatter’s size configuration boxes. You can now enter values in the KB, MB, and GB boxes that can reach up to 2 TB.
  • A lot of people were mistakenly using FATXplorer’s Backup & Restore feature to transfer content between drives. Since this ruins the destination drive’s Xbox 360 compatibility due to the Security Sector being overwritten with the source drive’s, a check has been added to make sure, during restoration, that the Security Sector in the backup file matches what is on the drive that the backup is being restored to, and a check has been added to make sure the backup file size is the same as the disk size.
  • If a USB with a 4K sector size is found in the USB formatter, FATXplorer will now display additional information that explains why it can’t be formatted. A lot of modern, large USBs come with 4K sector sizes, and the Xbox 360 OS doesn’t support them, so FATXplorer will now explain this to avoid confusion.
  • Specific formatters are now free to use.
  • Added a check box to the Devices tab: Device detection diagnostic logging. This determines whether detailed information about the device detection process is saved to DDDiagnostics.txt. You can use this output to diagnose problems with device detection.
  • The Windows Integration driver has been updated to fix several internal issues. You will need to update the driver, you’ll see an alert box when you open FATXplorer.

Breaking Changes

FATXplorer is now built on .NET Framework v4.5.2. This is important because, as a result of this change, FATXplorer will no longer work on Windows XP. FATXplorer now requires at least Windows Vista, but Windows 7 or 8 are recommended for the best experience. If you are an existing customer, have Windows XP, and are in desperate need of a fix or enhancement this version provides, please send in a support request and a custom version can be prepared for you that will still work on Windows XP. Please only do this if you have no Windows upgrade options. Windows XP is no longer secure and it would be in your best interest to upgrade to Windows 7 or 8.

If you aren’t sure if you have .NET Framework v4.5.2, you can download it here and the installer will install it if it’s missing.

Windows 10 compatibility & Price Change

If you are or will be using a pre-release version of Windows 10, FATXplorer should work fine on it, but you should refrain from using Windows Integration. The driver is not made for Windows 10 and may crash your OS, corrupt your file data, or just not work at all. Use Windows Integration at your own risk. All other FATXplorer features should work fine, though.

FATXplorer & the HDD Recovery Service have a new low price! A FATXplorer license is now $25, and the Recovery Service is now $15. This price change was made a few weeks ago, and is permanent.

Contact Form Fail

There has been an issue with the contact form this week. This also carried over to the recovery service form. It should be fixed now. If you did not get a response to your message, please re-send it now.

Download Stats

On June 4, 2013, a download counter was implemented to get an idea of how many times FATXplorer was downloaded per day and in which countries it is most popular. At the time of writing, FATXplorer has been downloaded 47,415 times from people all over the world! If you’re curious about the full statistics, check them out here: 64bit | 32bit


Enjoy the update! Expect a bigger one later this year.
