Here are the commands to modify MS Windows/DOS files and directories.
- Display file permissions. Replace filename with your file name.
> cacls filename ...filename NT AUTHORITYSYSTEM:F PCxxxxxxxxxxxxAdmin:F
- Modify permissions. Here we are granting full access to the user, replace user with desired user name.
> cacls filename /E /G user:F processed file: C:...filename
- Here we see the permissions have been reset:
> cacls filename ...filename PCxxxxxxxxxuser:F NT AUTHORITYSYSTEM:F PCxxxxxxxxxxxxxAdmin:F
