Tan68 is correct although it is easier to simply follow Pentax instructions. "Ensure that you extracted the .BIN file out of the ZIP (the .BIN file is the only thing that the camera wants)."

To extract (Unzip) a file, you normally just double click (or maybe right click) on the zip file and it will automatically "unpack". (It depends on your computer, but the basic process is very straight forward.) Then grab the resulting .bin file and copy it to your SD card.

For Windows, double clicking on the ZIP file lets me 'look inside' or see the contents of the ZIP as with any regular folder. A right-click show the pop-up menu with extract command. When extraction is started, there is a dialog box that allows the user to decide where to unZIP/extract the contents of the ZIP -- i don't figure this is instruction you require but just adding comments for whoever else reads through.

On my Windows PC the file Automatically downloaded to the Downloads Folder.

I moved the .zip file to a separate Folder* I set up for K-1 Firmware Updates (I have a separate folder for each Pentax camera I own), double-clicked the .zip file, and the .bin file self-extracted.

I moved the .bin file** to the formatted SD card and followed the Update Firmware procedure.


* I have the .exe or .zip of every FW Update held in camera-specific Folders. Since they are separate I won't have any -2.bin file naming issues.
** By using the move command the .bin file is removed from the Folder. If I ever need to redo the FW Update my Folder is 'clean' so I won't have any -2.bin file naming issues.
