Indeed, when I go to the C: drive and type cal, the program starts. Now I have installed two programs: CAL.EXE and VC.COM. I tested this first with a couple of simple standalone programs – Visicalc and DOS Cal:

The easiest way to do this is to just double click on its icon in the GUI, then copy and paste the files from the source directory or directories to the directory that the image is mounted on. To verify that the floppy had been formatted, I ran a hexdump in the Unix terminal.

Now you have a blank floppy image and are ready to add files to it. So insert the blank disk image in the VM and type format a: The next step is to format the file with an MS-DOS FAT filesystem. I took a screenshot of the output of dd for a visual: This can be done using dd, with the following command:ĭd if=/dev/zero of=floppy.img bs=1024 count=1440

img, or some other raw floppy image extension. The first thing you need to do is create a 1.44 MB empty file with an extension of. Well, now I’ve found a way to do just that, partly by doing some research on Google and partly by just figuring stuff out on my own. I came somewhat close to a solution by using Keka to archive directories as ISO files, but I was unable to create what I truly needed – a floppy disk image containing the archived contents of a directory. For a long time I have needed a way to transfer data into my DOS virtual machines.
