The “hidedotfiles” option was introduced in today’s update. This patch series, written by Konstantin Komarov of Paragon Software, has a “.” as a standard feature on any hidden folder in Linux systems, and NTFS attributes it to the “FILE_ATTRIBUTE_HIDDEN” feature set.
Due to MicrosoftWindowsThe system does not rely on “dotfiles” to hide files/folders, it uses the FILE_ATTRIBUTE_HIDDEN file attribute to determine whether something is hidden or visible. So when using a patched NTFS3 filesystem driver (or when those patches are mainlined) and using the “hidedotfiles” mount option, it basically sets this file attribute for any file created under Linux, Thus preserving the same hidden intent whether the filesystem is mounted under Windows or Linux.
This “hidedotfiles” behavior is not the recommended default, but requires the user to opt in to it if one wishes to set FILE_ATTRIBUTE_HIDDEN for “hidedotfiles”. The patch series is not currently on the mailing list, and it’s unclear if the patch improvements will be incorporated into the upcoming v6.1 merge window.
