those files I want to access on the HD20 when connected to my SE/30. I then use SheepShaver to copy/paste etc. I then run SheepShaver and attach the HD20 file to it as a mountable drive. I them copy my 'HD20' file from the Floppy EMU to my Mac Mini desktop, because I have found attempting the next few steps directly to the USB-mounted micro-SD card is unstable when I try to read/write to it directly from SheepShaver. I mount my micro-SD card from my Floppy EMU on my Mac Mini High Sierra.
