How to Deny Folder Permissions Using Command Prompt

With the increase in technology, the use of computers has become a necessity. We store a lot of personal information on our computers, from our favorite photos and media files to official documents. It’s no surprise that we care a lot about our privacy. We want to ensure that our personal data stored in folders on our desktops are protected and not accessible to others.

There are various methods to secure our personal data stored in folders, such as password protection and the option to hide folders.

However, these methods are not entirely secure and can be easily bypassed by hackers.

To ensure maximum security, we can use the command prompt to deny folder permissions.

Here’s A Trick To Deny All Permissions Of A Folder Using Command Prompt (CMD)

Using the command prompt, we can deny all permissions to a folder, preventing others from opening or deleting the folder.

Here’s how you can do it:

Step 1: Open Windows Command Prompt

Step 2: Change the directory to the target folder you want to deny access to

Step 3: Type “cacls folder_name /e /p everyone:n” and press Enter

Congratulations!

You have successfully denied all permissions to the selected folder. No one will be able to access or modify the folder, including yourself.

To regain permission, type “cacls folder_name /e /p everyone:f” and press Enter.

Understanding The Commands:

• cd – Change Directory
• cacls – Change Access Control Lists
• /e – edit
• /p – permissions
• everyone – every user
• f – full
• n – none

The above method is useful when we want to deny access to a particular folder permanently.

But what if we want to deny access temporarily? We can use the command prompt to remove folder permissions.

To remove folder permissions using the command line, follow these steps:

Step 1: Open Windows Command Prompt

Step 2: Change the directory to the target folder you want to remove permissions from

Step 3: Type “icacls folder_name /remove username” and press Enter

This command will remove the folder permissions for the specified user.

If you want to remove folder permissions for everyone, use “icacls folder_name /remove everyone” instead of “username.”

In some cases, we may want to restrict folder access for a particular user.

We can use the command prompt to revoke folder permission for a specific user.

Here’s how to do it:

Step 1: Open Windows Command Prompt

Step 2: Change the directory to the target folder you want to restrict access to

Step 3: Type “icacls folder_name /deny username:(X)” and press Enter

The above command will deny the specified user access to the folder.

If you want to revoke access for everyone, use “icacls folder_name /deny everyone:(X)” instead of “username.” Here, (X) represents the type of permission you want to deny.

For example, to deny write permission, use (W).

In some cases, we may want to prevent users from accessing a particular folder altogether.

We can use the command prompt to disable folder permission for everyone.

Here’s how to do it:

Step 1: Open Windows Command Prompt

Step 2: Change the directory to the target folder you want to disable access to

Step 3: Type “icacls folder_name /deny everyone:(X)” and press Enter

The above command will deny everyone access to the folder, including you. To regain permission, use “icacls folder_name /grant username:(X)” and press Enter.

Here, (X) represents the type of permission you want to grant.

Here is a simple example:

• There is a folder in E: drive named “Personal”

• Open the command prompt and type E: to change the directory to E drive.

Understanding The Commands:

• cacls- Change Access Control Lists
• /e- edit
• /p- permissions
• everyone- every user
• f-full
• n-none

Now that you have learned how to use the command prompt to deny folder permissions, let’s explore some additional ways to manage folder access using the command line.

How to Remove Folder Permissions Command Line

If you have previously granted permissions to a folder and want to remove them, you can do so using the command line. Simply open the command prompt and navigate to the folder you want to modify. Then, type the following command:

icacls “foldername” /remove “username”

Replace “foldername” with the name of the folder you want to remove permissions from and “username” with the name of the user you want to remove permissions for. This will remove all permissions previously granted to that user for the specified folder.

Deny Write Permission Command Line

If you want to deny write permission to a folder for a specific user, you can use the following command:

icacls “foldername” /deny “username”:(w)

Again, replace “foldername” with the name of the folder and “username” with the name of the user you want to deny write permission for.

How to Restrict Folder Access Command Prompt

If you want to restrict access to a folder, you can do so using the command prompt.

First, navigate to the folder in question using the command prompt. Then, type the following command:

icacls “foldername” /deny “username”:(r)

This will deny read access to the specified user for the specified folder.

How to Revoke Folder Permission Using Command Prompt

If you want to revoke all permissions for a specific user for a particular folder, you can use the following command:

icacls “foldername” /remove “username”

This will remove all permissions previously granted to that user for the specified folder.

icacls “foldername” /deny “username”:(d)

This will deny all access to the specified user for the specified folder.

To prevent folder access using the command line, you can use the following command:

icacls “foldername” /deny “username”:(rx)

This will deny both read and execute access to the specified user for the specified folder.

If you receive a “folder permission denied” error when trying to access a folder, it means you do not have the necessary permissions to access that folder. To grant yourself permission, you can use the following command:

icacls “foldername” /grant “username”:(f)

This will grant full access to the specified user for the specified folder.

Folder Permission Denied Using Command Prompt

If you receive a “folder permission denied” error when trying to access a folder, you can use the above command to grant yourself access to the folder using the command prompt.
