Post Anniversary Upgrade causes "unsupported reparse point"
After doing the Windows 10 Anniversary Update (Windows 10 build 14393, version 1607), many of the files accessed through NTFS-3G showed as symbolic links with a "unsupported reparse point" error. Looking at the file while booted in Windows shows that the file is a hard link, not a reparse point. Specifically, the PowerPoint recipe given here gives me this:

Code:
PS C:\Windows\Fonts> Get-ItemProperty -Path  YuGothR.ttc  | Format-list -Property * -Force


PSPath            : Microsoft.PowerShell.Core\FileSystem::C:\Windows\Fonts\YuGothR.ttc

Also, though NTFS-3G I got the reparse data:

Code:
etfattr -h -e hex -n system.ntfs_reparse_data YuGothR.ttc
# file: YuGothR.ttc
system.ntfs_reparse_data=0x170000801000000001000000020000000100000000000000

Hi,

I have posted a full reply for you on the Fedora bugzilla (#1377049). To sum up for other users interested : on some computers Windows 10 compresses the system files and a specific reparse point type triggers the decompression.

For accessing such files from ntfs-3g you need ntfs-3g-2016.2.22AR.1 (currently packaged by some distributions) and the decompression plugin developed by Eric Biggers (not yet packaged by distributions).

See http://jp-andre.pagesperso-orange.fr/ju ... html#other

Regards

Jean-Pierre
