You can copy things from the floppy to ZIP one by one (load them from the floppy, then save to the ZIP). This is long and time-consuming.

There is, however, a Roland Database Manager program which allows you to import styles and MIDI files from floppies and or ZIPs into the PC-based database manager (and also change names, but not contents), and then re-export them on the ZIP.

This is useful also copy the contents of ZIPs from one disk to another, plus keep a backup on your PC's hard disk.
