I ha ve a KN5000 which I have owned for 15 years. Never really used it.

Replaced the drive with gotek one couple of years ago. Now I'm going to try new styles for the kn5000. My worry is that the Custom section of styles contains last owners custom styles, which i would like to save in case I download new styles from here, and they replace my old custom styles.

So how can i save the Custom styles? Also how big usb stick should i use with the gotek? And how to format the disk for the gotek, so that it can be used by my pc AND kn 5000?

Custom styles are a completely separate 'file' set up so ordinary style files will not dislodge custom styles.
