In computingcacls and its replacement, icaclsare Microsoft Windows native command line utilities capable of displaying and modifying the security descriptors on folders and files. An access control list is a list of permissions for securable object, such as a file or folder, that controls who can access it. The cacls. Windows Server Service Pack 2 and later include icaclsan in-box command-line utility that can display, modify, backup and restore ACLs for files and folders, as well as to set integrity levels and ownership in Vista and later versions.

It only takes a minute to sign up. I'm trying to reset permissions on user directories and having a bit of trouble with the last step of my script. My script basically takes ownership of the entire user directory, resets the permissions on all files and folders for the directory, explicitly grants the permissions I need, stops all inheritance of permissions from parent folders, sets the rightful owner specified user for all files and folders, and then removes the permission I gave to myself so that I could operate on the files.
Does anyone know of any other way to accomplish this? An observation first: Every time you block inheritance you're cutting yourself off from future flexibility. I avoid blocking inheritance at all costs. The last permission doesn't inherit down into the subfolders. At each subfolder, inheritance remains enabled and you simply specify the user with "Modify" or "Full Control" rights depending on how you feel about users being able to set permissions inside their home directory.
Typically I set that last permission by adding "Authenticated Users" in the non-"Advanced" Security properties sheet, unchecking the "Read" and "Read and Execute" check boxes. That's about the easiest way, in terms of number of clicks, to set it. This is my SOP for user home directories, redirected "My Documents", "Desktop", etc folders, and for roaming user profile directories.
It works great. It's easier to solve a certain class of user problems if you can get to their files. It's a pain to "take ownership" and can be quite slow if there are a large number of files present, too. Obviously, EFS isn't the only show in town. Encryption is the real answer to solving the "limit the network Administrator's access" problem no matter how you slice it.

I've given up trying to win the argument with people by way of logic. It seems to be an emotional issue with some people.
Blocking inheritance in permission hierarchies is a sure sign that something about the design is "broken" inverted, etc. First, thanks for your script excerpt. I've been working on the same thing but was stuck in a different place. On my SBS box, the below code works for me assuming it's run elevated, of course. Hopefully it'll work for you as well.
I need your help to modify this command according to my requirement if that is technically possible.
I have this command which works fine for me in perspective of applicability of required permissions but I cannot add exclude function in this.

Aug 14 '09 at In this article, we will learn how to set or reset NTFS permissions of a file or folder in a Windows operating system, with icacls command.
Or we may have to run a software that, for permission issue, does not work as it should. We may also need to access a file that came from an old backup or another computer and was therefore created with a different user; even then, it will not be possible to access it.
Icalcs is the replacement for cacls Change Access Control Listsa command-line utility that allows you to show and perform some operations on ACL for files or directories. ACL Access Control List is a list of permissions for a filesystem object and defines how its security is controlled by managing who and how it can be accessed. Actually, operations on ACL are not the only ones possible with this tool. What makes it a powerful tool is also the ability to perform backup and restore operations on ACL for files or directories, or to search for files that have a specific user as owner.
And in addition, in the event that an ACL is damaged or destroyed, with icacls you can restore it by resetting it and setting default permissions or inheriting those of the parent. Imagine that we have an external hard disk on which a study made in was stored, and we want to recover it, but we do not have complete control. One solution is, therefore, to use the reset function of Icalcs. But pay attention to the following steps. We must therefore first become the owner of the folder with the takeown command:.
Only the user named Peter has access to the folder, and we want to give grants also to the federica user. For more options, see the official page. A very simple operation from a point of view: information about the ACLs are saved in a file that can be used in case of need to restore a previous situation.
However, it should be noted that data on access rights, especially in shared folders, can be very variable over time. We could then find ourselves in a situation where we are going to restore a situation that is different from reality or even inconsistent. Moreover, the file that is created, openable and readable with a common text editor, seems to be a Unicode text. As you can see, in restore command case we will not use filediprova.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. How can I grant permissions to a user on a directory Read, Write, Modify using the Windows command line? You should use icacls instead. For complete documentation, you may run " icacls " with no arguments or see the Microsoft documentation here and here.
Use cacls command. See information here. For example grant Rocky Full F control with following command type at Windows command prompt :. I try the below way and it work for me: 1. So that the files can become my own access and it assign to "Delete" and then I can delete the files and folders. Although most of the answers posted in reply to the question have some merit, IMHO none of them give a complete solution.
The following might be a perfect solution for Windows 7 if you are locked-out of a folder by corrupted permission settings:. Specifying the user "Everyone" sets the widest possible permission, as it includes every possible user. This is only a precaution, as there is often no DENY setting present, but better safe than sorry. The " OI " and " CI " parameters also add recursion, applying these changes to sub-objects created subsequently.
The Windows 10 command line above was kindly suggested to me today, so here it is. I haven't got Windows 10 to test it, but please try it out if you have and then will you please post a comment below. The change only concerns removing the DENY setting as a first step. There might well not be any DENY setting present, so that option might make no difference. I only have an English install of Windows, so I can't test this proposal, but it seems reasonable.
I struggled with this for a while and only combining the answers in this thread worked for me on Windows 10 : 1.
Open cmd or PowerShell and go to the folder with files 2. Just in case there is anyone else that stumbles on this page, if you want to string various permissions together in the one command, I used this:. With an Excel vba script to provision and create accounts. I was needing to grant full rights permissions to the folder and subfolders that were created by the tool using our administrators 'x' account to our new user.
Permissions replace previously granted explicit permissions. Without :r, permissions are added to any previously granted explicit permissions. What this gave me was a folder on this server that the user could only see that folder and created subfolders, that they could read and write files.
As well as create new folders. You can get official distribution from Microsoft Support Page. Note: You have to create same domain username in csv file otherwise you will get permission issues.Grants specified user access rights.
