In Windows networks, you can set sharing permissions for drives and folders. NTFS permissions, as its name implies, are available to drives formatted with NTFS, which affects local users as well as network users. To be specific, you can only access files or folders with permissions, regardless of where the user is connecting.
And the files in NTFS drives have a Security attribute compared to those in FAT32 formatted drives. You can access it with this approach: open a file in the NTFS partition > right-click it and select Properties > General > Advance. You could see two options there: File attributes and Compress or Encrypt attributes.
By default, almost all system files, system folders, and even registry keys are owned by a special user account called "RrustedInstaller", and other users only have read permission. And it will check the permissions when you access specific files or folders, if you don't have the permission, it will not allow you to access them. So you need to restore NTFS permission to gain it.
Also, there is a possibility that you lose permission to access specific files or folders, in this case, you can only restore NTFS permission to get it.

It's the replacement for cacls (Change Access Control Lists), and allows you to define who and how users access filesystem objects. Besides, you still have the ability to backup and restore NTFS permission and reset its to default permission or inherit from the parent folders if the NTFS permissions mess.
