I would like to create disk images for the floppy drive or a hard drive. From what I have been reading I need the program  mkdskimg.  This program is not part of the windows download package. Is there a windows copy of this program or alternatively, what are the instructions to create a disk image and populate with files of my choice?

There are some programs on http://www.retroarchive.org/ that i would like to put on floppy and use. Files from this archive come are not stored as dsk images.

Thanks for your help.

Ken,
my strategy is to take a copy of an existing image, rename it, and use cpmtools to delete the file from it and add new files.

cpmtools includes a tool mkfs.cpm which is used to create new disk images, similar as mkdskimg.

For using mkdskimg on Windows you need to install Cygwin and/or WSL, with this you can build
everything also on Windows systems.

This actually brings me to how to backup to a suitable format....  of image.

I currently am setting up to backup something like 500 floppy disks (possibly more unfortunately) to a suitable disk.image.format
I was intending to use something like a "greaseweazle" to read. These are ALL 8 inch floppies, majority being double sided high density disks. so round 1M each, which should be easy enough to store in a database.

Any suggestions as to disk.image.formats suitable ?

It would also be great if we had somewhere to share IMSAI floppy images. Would ppl be willing to use the TOSEC archive?
