What permissions are needed to modify drives?
SymptomsArticle Summary: This article discusses NTFS permissions and share permissions in Windows and how they work together to regulate access to files and folders. Show
Windows provides two sets of permissions to restrict access to files and folders: NTFS permissions and share permissions.
The most important thing to remember about NTFS permissions and share permissions is the manner in which they combine to regulate access.
You can undo any changes to privilege settings for a user or group in the Sharing & Permissions section since opening the Info window. Before closing the Info window, click the Action pop-up menu at the bottom of the window, then choose “Revert changes.”One of the most critical security concepts is permissions management: ensuring that proper permissions are set with users – and that usually means knowing the difference between share and NTFS permissions. Share and NTFS permissions function completely separately from each other, but ultimately serve the same purpose: to prevent unauthorized access.

Here are key differences between share and NTFS permissions so you’ll know what to do. What is NTFS?A file system is a way of organizing a drive, indicating how data is stored on the drive and what types of information can be attached to files, such as permissions and file names. NTFS (NT File System) stands for New Technology File System (NTFS). NTFS is the latest file system that the Windows NT operating system uses for storing and retrieving files. Prior to NTFS, the file allocation table (FAT) file system was the primary file system in Microsoft’s older operating systems, and was designed for small disks and simple folder structures. NTFS file system supports larger file sizes and hard drives and is more secure than FAT. Microsoft first introduced NTFS in 1993 with the release of Windows NT 3.1. It is the file system used in Microsoft’s Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000, and Windows NT operating systems. NTFS PermissionsNTFS permissions are used to manage access to the files and folders that are stored in NTFS file systems. To see what kind of permissions you will be extending when you share a file or folder:
All then you’ll navigate this window: Besides Full Control, Change, and Read that can be set for groups or individually, NTFS offer a few more permission options:
If you’ve ever involved in permissions management within your organization, you’ll eventually encounter ‘broken’ permissions. Rest assured, they’re repairable. Share PermissionsWhen you share a folder and want to set the permissions for that folder – that’s a share. Essentially, share permissions determine the type of access others have to the shared folder across the network. To see what kind of permissions you will be extending when you share a folder:
And you’ll navigate to this window: There are three types of share permissions: Full Control, Change, and Read.
A Caveat on Share PermissionsSometimes, when you have multiple shares on a server which are nested beneath each other, permissions can get complicated and messy. For instance, if you have a “Read” folder in a subfolder share permission but then someone creates a “Modify” share permission above it at a higher root, you may have people getting higher levels of access then you intend. There’s a way around this, which I’ll get to below. How to Use Share and NTFS Permissions TogetherOne of the common questions that comes up when you’re configuring security is “what happens when share and NTFS permissions interact with each other?” When you are using share and NTFS permissions together, the most restrictive permission wins. Consider the following examples:If the share permissions are “Read”, NTFS permissions are “Full control”, when a user accesses the file on the share, they will be given “Read” permission. If the share permissions are “Full Control”, NTFS permissions are “Read”, when a user accesses the file on the share, they will still be given a “Read” permission. Managing NTFS Permissions and Share PermissionsIf you find working with two separate sets of permissions to be too complicated or time consuming to manage, you can switch to using only NTFS permissions. When you look at the examples above, with just three types of permissions setting, shared folder permissions provide limited security for your folders. Therefore, you gain the greatest flexibility by using NTFS permissions to control access to shared folders. Moreover, NTFS permissions apply whether the resource is accessed locally or over the
network. You can then make whatever changes you want to the NTFS permissions without having to worry about the share permissions interfering with your changes.

What does modify permission allow?Modify: Allows users to read and write of files and subfolders; also allows deletion of the folder.
What are the 3 types of permissions?Files and directories can have three types of permissions: read, write, and execute: Someone with read permission may read the contents of a file, or list the contents of a directory. Someone with write permission may modify the contents of a file, including adding, changing, or deleting file contents.
What permissions are required to rename existing files?You can rename a file or folder when either of the following permission is assigned to you1: The Delete permission for the file or folder to be renamed. The Delete subfolders and files permission for the parent folder of the file or folder to be renamed.
What are the six types of permissions?Permission Types
There are basically six types of permissions in Windows: Full Control, Modify, Read & Execute, List Folder Contents, Read, and Write.
