If you have a Windows 10 installation, you might not be able to read all files on its NTFS partition. Under certain conditions, Microsoft compresses system files with new compression algorithms which the ntfs-3g driver can’t currently read. Files are displayed with question marks when listed using ls, and you’ll see Input/output error or unsupported reparse point when trying to access these files. Here’s an example:
$ ls -l Windows ... drwxrwxrwx 1 kparal kparal 0 Sep 15 09:33 ModemLogs -????????? ? ? ? ? ? notepad.exe drwxrwxrwx 1 kparal kparal 0 Dec 14 21:57 OCR drwxrwxrwx 1 kparal kparal 0 Sep 15 09:33 'Offline Web Pages' drwxrwxrwx 1 kparal kparal 16384 Dec 14 14:17 Panther drwxrwxrwx 1 kparal kparal 0 Sep 15 09:33 Performance -rwxrwxrwx 1 kparal kparal 984966 Feb 13 23:15 PFRO.log drwxrwxrwx 1 kparal kparal 0 Sep 15 09:33 PLA drwxrwxrwx 1 kparal kparal 49152 Dec 14 21:59 PolicyDefinitions drwxrwxrwx 1 kparal kparal 163840 Feb 14 22:41 Prefetch drwxrwxrwx 1 kparal kparal 4096 Dec 14 14:15 PrintDialog -????????? ? ? ? ? ?

Fortunately, there’s a ntfs-3g-system-compression plugin that allows you to read those files:
$ ls -l Windows/notepad.exe -r-xr-xr-x 3 kparal kparal 254464 Sep 15 09:28 Windows/notepad.exe
The new package is now proposed as an update in Bodhi, but in a week or so you should be able to install it with a simple:
$ sudo dnf install ntfs-3g-system-compression
Enjoy.

Thanks for the tips. Will it be default installed on next Fedora release?
Yes, it is now installed by default. It should also be pulled in automatically for everyone who already has the ntfs-3g package installed.
