How to Fix the "Request Permission from SYSTEM to Modify This Folder or File" Error

When attempting to modify, delete, or move files on a Windows computer, users may sometimes encounter the error message, “Request permission from SYSTEM to modify this folder or file.” This issue typically arises due to access restrictions or permissions set by the system to protect important files.

Why This Error Occurs

This error often appears when a file or folder is restricted for the following reasons:

  • The file is used by the operating system, and modifications may impact its functionality.
  • The user lacks the necessary permissions to perform actions on this file or folder.
  • Administrative or Windows system protection settings are restricting access.

Ways to Resolve This Issue

1. Take Ownership of the File or Folder

Sometimes, access can be gained by changing the file or folder owner:

  1. Right-click the folder or file in question and select “Properties.”
  2. Go to the “Security” tab and click “Advanced.”
  3. In the "Owner" section, click “Change” and choose your account.
  4. Check the box next to “Replace owner on subcontainers and objects” to apply changes to all subfolders and files.
  5. Click “Apply” and then “OK.”

2. Modify Permissions for Your Account

If you’re already the owner but still can’t make changes, try updating access permissions:

  1. Open the “Security” tab in the file or folder properties.
  2. Click “Edit” to open the list of users.
  3. Select your account and check the box next to “Full control.”
  4. Click “Apply” and then “OK.”

3. Use Command Prompt to Adjust Permissions

You can also modify permissions through the Command Prompt with administrator privileges:

  1. Open the Command Prompt as an administrator by searching for “cmd” in Windows search, then selecting “Run as administrator.”
  2. In the Command Prompt, enter the following commands, replacing Folder_Path with the path to the folder:
takeown /F "Folder_Path" /R /D Y
icacls "Folder_Path" /grant %username%:F /T

These commands change the folder owner and grant full access to your user account.

4. Disable Windows Security Temporarily

In some cases, built-in security features may restrict access to certain files. Try temporarily disabling Windows Defender or any third-party antivirus software to see if they are causing the issue.
