2 programs you might want to try are diskdupe for the MAC, It works like the diskcopy programs that DOS has always had. Executor will only read 1.4md disks but if you use a diffrant program that will format a 1.4mb disk so that half the diks will look like an 800k MAC disk and the other side will be DOS formated. Then you can use this disk with the MAC copy program. Good Luck!
