You open it on the PC, select the CAB file, and then click on the zipped folder icon to extract the contents. It'll place the files inside subfolders "Program Files," "Windows," etc inside the folder you've specified to extract them to. This is to show you where they go on the device.
(Of course, you can substitute the internal NAND storage for Program Files.
