## Start Policy Tool

> To start Policy Tool, simply type the following at the command line:

> >     policytool

> This brings up the Policy Tool window.

> Whenever Policy Tool is started, it tries to fill in this window with policy information from what is sometimes referred to as the "user policy file". The user policy file is by default a file named `.java.policy` in your home directory. If Policy Tool cannot find the user policy file, it reports the situation and displays a blank Policy Tool window (that is, a window with headings and buttons but no data in it), as shown in the following figure.

> This figure has been reduced to fit on the page.
> Click the image to view it at its natural size.

> You can then proceed to either open whatever policy file you want to work on or create a new policy file.

> The first time you run the Policy Tool, you will see the blank Policy Tool window, since a user policy file does not yet exist. You can immediately proceed to create a new policy file, as described in the next step.
