Back-up your SD card files before updating so you can always revert to your original settings. Now that you have access to the files, locate the SD Card Structure folder in the folder you just extracted. This folder will have two folders Compound and K'Tana, select the folder based on what nozzle you currently have mounted on your printer. In both of these folders are the files you want to copy to your microSD card. This should be four folders: sys, gcodes, macros and www. Plug in the microSD card into your computer with the microSD card reader and copy the files onto it. Your SD card should look like this. Using WinDiff or a similar program to distinguish differences between the latest SD card release and your files might be a good idea.
