Probably need some more info on your Machine. On a vanilla single Disk A1000 this is a challenge. You can format a 720k floppy on a PC copy the files you need onto that and then read it on the Amiga using the MSDos Disk Device. But to get that device On 1.3 you will need a way to move files. Vicious circle. Best option is to get a Mate with a networked Amiga with HD and a working FDD to create the Ncomm Disk for you.
