This is a SIF file that contains appliance artifacts needed to build a winzip appliance.
This is the SIF demonstrated in the video
SIF can be used to ship windows appliance artifacts without including the Windows ISO. This helps to deal with Windows licensing constraints.
Please refer to the video for more information on SIF.
To use this SIF file, download it to your Studio location. Then, type
studiocli --sif --import winzip-app.sif --b /
This should untar the appliance artifacts into the right location. Then, login to Studio web console and view the winzip build profile. Provide the Windows 2008 R2 ISO and build using a provisioning engine.
