I am sure they could have done a better job with this feature, but perhaps it's rare enough to not be worth the processing overhead of having to always scan for "same name but different case" anytime the Linux OS requests to access/write a file on NTFS. Therefore, there is no way to make NTFS-3G's driver behave exactly like Windows (showing case, but not allowing duplicate files of different case). Most likely, they're literally just telling their own internal "filesystem file object" to always read/convert its "name" field as lowercase, which is why it is such a harsh and completely useless option. They have a very half-assed option named "ignore_case" in the driver, but if you read the manpage for it, that is just a quick and dirty hack, which just makes all existing and new files display and save as lowercase. Windows won't know which file/folder you want to access. So if you create files/folders that only differ by their case, it will work fine in Linux, but as soon as you try to access that location on Windows, you will have massive issues. Windows uses a "layer" on top of NTFS which forces everything to be case-insensitive. NTFS itself is case sensitive and supports "duplicate" file/folder names if they have different case, such as "pictures" and "Pictures". I just want to mention one more thing: There is one more problem that can affect Windows compatibility. :-) So this is a sane new default and I hope it stays forever. It could lead to some minor confusions (like "Woah, why did my 127.0.0.1:80_udp.conf file get renamed to 127.0.0.1_80_udp.conf?"), but that's way better than writing corrupt filenames to Windows disks. With this new option, NTFS-3G automatically translates them to an underscore when you try writing to the NTFS disk. The only real reason for NTFS on Linux is to access internal/external Windows-formatted drives, so it's very important that we have windows_names enabled to protect against forbidden characters such as : and \ in filenames. This is a very good change, thank you for doing this. The forbidden characters are the nine characters " * / : ? \ | and those whose code is less than 0x20, and the reserved names are CON, PRN, AUX, NUL, COM1.COM9, LPT1.LPT9, with no suffix or followed by a dot.Įxisting such files can still be read (and renamed). or the last character is a space or a dot, it contains some not allowed character, This option prevents files, directories and extended attributes to be created with a name not allowed by windows, because The option windows_names may be used to apply Windows restrictions to new file names. This is perfectly legal on Windows, though some application may get confused. This means that filenames are case sensitive and all characters are allowed except '/' and '\0'. While the ntfs-3g driver handles all of them, it always creates new files in the POSIX name‐space for maximum portability and interoperability reasons. NTFS supports several filename namespaces: DOS, Win32 and POSIX.
