Setting file permissions from command line in windows

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
