Software Packager for Linux and UNIX › Create a Delta Package

Create a Delta Package

A delta package contains only those files that differ between two versions of the same PIF package. These two versions are called preversion and resulting version. The delta package is installed on the target computer to update an already installed preversion to the resulting version of the PIF package.

Creating a delta package requires the existence of two versions of the same PIF package.

To create the delta package of two package versions

1. Select the resulting version of the PIF package in the project pane.
2. Select the PIF file (*.@pif) of the resulting version of the package on the Media tab in the subproject pane.
3. Right-click the selected entry and select Delta from the context menu.

   The Build delta package dialog appears.

4. Select the preversion from the drop-down list.
5. Click Build.

   The delta package is built in the same folder as the resulting version of the package. The name of the corresponding delta package PIF file is displayed in the media table.

   The name of the delta package PIF file is automatically created by the Packager, and is structured as follows:

   prodname.platform.preversion-resultingversion.@pif
