How are inherited permissions affected when a folder is moved from an NTFS partition to a FAT partition on the same disk?
NTFS and share permissions are both often used in Microsoft Windows environments. While share and NTFS permissions both serve the same purpose — preventing unauthorized access — there are important differences to understand before you determine how to best perform a task like sharing a folder. Here are the key differences between share and NTFS permissions, along with some recommendations for when and how to use each of them. Show
What Are NTFS Permissions?NTFS (New Technology File System) is the standard file system for Microsoft Windows NT and later operating systems; NTFS permissions are used to manage access to data stored in NTFS file systems. The main advantages of NTFS share permissions are that they affect both local users and network users and that they are based on the permissions granted to an individual user at the Windows logon, regardless of where the user is connecting from. There are both basic and advanced NTFS permissions. You can set each of the permissions to “Allow” or “Deny” to control access to NTFS objects. Here are the basic types of access permissions:
Share permissions manage access to folders shared over a network; they don’t apply to users who log on locally. Share permissions apply to all files and folders in the share; you cannot granularly control access to subfolders or objects on a share. You can specify the number of users who are allowed to access the shared folder. Share permissions can be used with NTFS, FAT and FAT32 file systems. There are three types of share permissions: Full Control, Change and Read. You can set each of them to “Deny” or “Allow” to control access to shared folders or drives:

Using Just One Set of PermissionsIf you feel that working with two separate sets of permissions is too complicated, you can use just NTFS share permissions. Simply change the share permissions for the folder to “Full Control,” and then you can make whatever changes you want to the NTFS permissions without having to worry about the file share permissions interfering with them. SummaryUnderstanding the differences between Share and NTFS permissions enables you to use them together to secure access to local and shared resources.

What happens to permissions if I move a file from NTFS to FAT32?When moving a folder or file between different NTFS partitions, the file or folder will inherit the destination folder permissions.
What happens when a folder with NTFS permissions is copied to shared folder on a FAT volume?What happens when a folder with NTFS permissions is copied to shared folder on a FAT volume? The folder inherits the share permissions, but loses the NTFS permissions.
How does inheritance work with NTFS permissions?NTFS Permission Inheritance
Opposed to share level permissions, NTFS permissions offer the possibility to let files and subfolders inherit NTFS permissions from their parent folders. The inheritance chain can be interrupted at any level, from the top down to a file, by disabling inheritance.
