I created images files for the DOS 6.22 and Windows FWG 3.11 floppy disks. For Windows 95, 98, XP, and later I created ISO files for the original CDs. When I create virtual machines I just mount appropriate the image files. Note some of these ISO files are not bootable so I also had to create additional bootable floppy image files.
I also have images of the floppies made by WinImage which can run on Win10/Win11 plus a USB 3.5" floppy drive. I have a USB ODD for the Notebooks that came without one.
