How to Open Locked (Inaccessible) Folder - Free Online Tutorial

In this tutorial, we are going to see how to access a Locked Folder on an NTFS Volume (Drive) which may be corrupted due to File System permission issues. Let us unlock it now...

If you get an error message like this while opening a folder on your Windows PC, just follow this tutorial...

Note: You must be an Administrator on your PC to do this operation...

Even after clicking Continue, you will be denied to open the folder...

So, now we have to check the NTFS Security Settings for the particular folder. So, right click and select Properties...

NTFS Permissions

In any Windows network, you can set sharing permissions for drives and folders. On that network, each user can choose to share entire drives or individual folders with the network.

NTFS (NT File System) permissions are available to drives formatted with NTFS. The advantage with NTFS permissions is that they affect local users as well as network users and they are based on the permission granted to each individual user at the Windows logon, regardless of where the user is connecting.

NTFS is the standard file system of Windows NT and all Windows operating systems that have come after it. Windows 2000 and older introduced some far-reaching changes that included control over inherited permissions and how permissions were configured to share files and folders. You use shared folders to provide network users with access to file resources.

Administrators can use the NTFS utility to provide access control for files and folders, containers and objects on the network as a type of system security. Known as the "Security Descriptor", this information controls what kind of access is allowed for individual users and groups of users.

Along with the additional functionality that NTFS provides comes the potential for complex configurations that can lead to administration headaches. If you don't have a thorough understanding of various permissions and their relationships, it can be difficult to sort out a permission problem when it occurs.

Now go to Security Tab... It will show you up the Standard Permissions.

Standard Permissions

Standard permissions are those permissions that control a broad range of detailed permissions. The most popular and infamous standard permission is Full Control. This is what everyone wants, but in reality very few should get. Full Control allows the user that is granted this suite of permissions to do virtually anything to the object the permissions are associated with. The other standard permissions include the following:



Read & Execute

Folders have the same standard permissions as files, except there is one additional standard permission “List Folder Contents.”

When you look at Registry keys, printers, and Active Directory objects, there is a totally different set of standard permissions for these objects. The security tab of each object will list the standard permissions, as shown in Figure 1 for a typical organizational unit (OU) within Active Directory.

Here you can see that the folder is lost or corrupt Security Properties... Now we have to take Ownership of the folder to bring them back to the normal... So, click Advanced...

Advanced Permissions

Advanced permissions are the detailed permissions that are grouped together to create the standard permissions. Since advanced permissions are used in combinations to create the standard permissions, there are more of them overall. For a file, here is a list of the advanced permissions:

Full Control
Traverse Folder/Execute File
List Folder/Read Data
Read Attributes
Read Extended Attributes
Create Files/Write Data
Create Folders/Append Data
Write Attributes
Write Extended Attributes
Read Permissions
Change Permissions
Take Ownership

Now click Change on the Owner section...


Now, enter your Current Login User Name (Full Name) exactly without spelling mistake, and click Check Names... If it returns your User Name followed by your Computer Name or Domain Name correctly, you did it well, and now you can click OK...


Now check (tick) the both check boxes as shown in the image to replace the permissions for it's child objects (folders and files inside this folder)... And click OK. Now click OK on the Security Tab of the Properties Window to complete the operation. Now you can see that you can able to open the locked folder now. Note: To make it accessible by All Users on your Computer, again open,

Properties -> Security Tab -> Advenced -> click Enable Inheritance -> check (tick) Replace child object permissions check box -> click OK -> click OK.....

Done... Enjoy Computing...
