Problem
You want to modify permissions in Windows from the DOS prompt command line.
Solution
Use cacls
cacls /?
Example
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:FPCxxxxxxxxxxxxAdmin:F
- Modify permissions. Here we are granting full access to the user, replace user with desired user name.
> cacls filename /E /G user:Fprocessed file: C:...filename
- Here we see the permissions have been reset:
> cacls filename...filename PCxxxxxxxxxuser:FNT AUTHORITYSYSTEM:FPCxxxxxxxxxxxxxAdmin:F
