jtan2000,
I've downloaded those *.7z packaged files and extracted them. The main files in those packaged
files are *.IMD and *.IMA or *.IMG. The *.IMD files are a format produced by Dave Dunfield for his
IMAGEDISK Software. Imagedisk and Dave's utilities can extract the Sector Dump of the *.IMD
images. I've processed those files with my A.BAT file.
IMA, RAW, and IMG are Sector Dumps (for these images 40 Tracks, 512 Bytes per Sector and 8 Sectors).
A.BAT contains
Code:
IMDA IBMEXPLR.IMD > IBMEXPLR.TXT
IMDA DISK01.IMD > DISK01.TXT
IMDU IBMEXPLR.IMD IBMEXPLR.RAW /B /E /D >> IBMEXPLR.TXT
IMDU DISK01.IMD DISK01.RAW /B /E /D >> DISK01.TXT
This gives a lot more information on the type files, the number of tracks, Sectors, Bytes per Sector,
Sector layout, Number of sides, and Bit rate 250kbps, and Density = Double Density.

Older CP/M and DOS Archiving Software:
*.IMD IMAGEDISK by Dave Dunfield
*.TD0 TELEDISK by Chuck Guzis = SYDEX
If you have an older computer that supports Floppy Drives, TELEDISK, IMAGDISK, dd for DOS,
LIBDSK for DOS, and DISKIMAGE can write your image(s) to Floppy.
You can also use any of the Fluxwriters to write Floppy's: Kryoflux, Catweasle, Fluxengine, GreaseWeazle,
SuperCard Pro, and Disk Ferret will write Floppy's. There may be other Flux Writers too!
