After creating TUTOR2.ZIP and the “Add” dialog box is displayed, select the files or directories you want to archive and press the “Add” button.

Now compression progress window will be shown. After the compression is finished, you will be able to work with PowerArchiver again.

If you wish to stop the compression process, simply click “Cancel” on progress window and when the confirmation dialog box appears, click “No”. This may result in a broken archive however, and should not be done unless absolutely necessary.

Another way to add files is to drag them from Windows Explorer or from the Desktop onto PowerArchiver.
