Modifying file permissions in Windows

1. Go to the file or folder that you want to edit the permissions for.
2. Right-click it and select Properties.
3. Go to the Security tab. Here, you’ll see a list of users or groups with their current permissions.

4. Click the Edit button to open the Permissions window.
5. Select the user or group you want to modify permissions for.
   • If the user or group isn’t listed, click Add. Type the user or group name in the field and click Check Names > OK.
   • If you want to prevent the existing user or group from accessing the file or folder, click Remove.
6. After selecting the user, check the boxes for the permissions you want to grant or deny under the Permissions section.
   • Full control: Allows complete access, including read, write, execute, and delete permissions
   • Modify: Allows reading, editing, and deleting the file or folder but not changing permissions
   • Read & execute: Allows viewing the file or folder and running applications
   • List folder contents: Allows viewing the file or folder name but no access
   • Read: Allows access to the file or folder but no edits
   • Write: Allows editing data but no deletions
7. Use the Allow or Deny check boxes as needed.

1. Click Apply to save the changes, then click OK to close the Permissions window.

   • Change the ownership of the file or folder to another user or group.
   • Edit the advanced file or folder permissions and set conditional access.
   • View the effective permissions for the user, group, or device.
   • Set auditing conditions for file or folder permission changes.
3. Review the updated permissions under the Security tab, then click OK to exit.
