Well from what I can tell (and I'm not an expert). Most other supposed image formats (Alcohol/Blindwrite) are actually just .ISO's even tho there extensions are different and I've actually used there respective images with DosBox. Now where you'll get into trouble is if you want to use CD Audio then you'll need to use a .CUE/BIN CD image format....other than that any CD image format should work. If I'm wrong then you can always mount your CD image with Daemon Tools and then mount the virtual CD through DosBox.

As for floppy image backup I always use the wonderfull "Winimage", although there are tons of freeware floppy imaging tools out there, like rawwrite.

Have you read the README file? It's all in there.

IMGMOUNT
A utility to mount disk images and CD-ROM images in DOSBox.

IMGMOUNT DRIVE [imagefile] -t [image_type] -fs [image_format]
-size [sectorsbytesize, sectorsperhead, heads, cylinders]

imagefile
location of the image files to mount in DOSBox. The location is on a
mounted drive inside DOSBox. CD-ROM images can be mounted
directly as well. They don't need to be a mounted drive.

-t
The following are valid image types:
floppy: Specifies a floppy image or images. DOSBox will automatically
identify the disk geometry ( 360K, 1.2MB, 720K, 1.44MB, etc).
iso: Specifies a CD-ROM iso image. The geometry is automatic and
set for this size. This can be an iso or a cue/bin.
hdd: Specifies a harddrive image. The proper CHS geometry
must be set for this to work.

-fs
The following are valid file system formats:
iso: Specifies the ISO 9660 CD-ROM format.
fat: Specifies the image uses the FAT file system. DOSBox will attempt
to mount this image as a drive in DOSBox and make the files
available from inside DOSBox.
none: DOSBox will make no attempt to read the file system on the disk.
This is useful if one needs to format it or one wants to boot
off of the disk using the BOOT command. When using the "none"
filesystem, one must specify the drive number (2 or 3,
where 2 = master, 3 = slave) rather than a drive letter.
For example, to mount a 70MB image as the slave drive device,
one would type:
"imgmount 3 d:\test.img -size 512,63,16,142 -fs none"
(without the quotes) Compare this with a mount to read the
drive in DOSBox, which would read as:
"imgmount e: d:\test.img -size 512,63,16,142"

-size
The Cylinders, Heads and Sectors specification of the drive.
Required to mount hard drive images.

An example of CD-ROM images:
1a. mount c /tmp
1b. imgmount d c:\myiso.iso -t iso
or (which also works):
2. imgmount d /tmp/myiso.iso -t iso

What would be cool is if we had a program running on our desktop that analyzes actions taken and has a database of actions taken before in certain situations and then provides suggestions. Of course there would be privacy issues but I suppose you could make it one-way. That would be an extremly cool app but it would probably requires an extremly intelligent AI and mainframe processor cycles.....oh well....guess we'll have to wait another 10-15 years.....hopefully by then we won't have to remind people to read the readme....since the readme will be reading them!

Eh... Clippy? 😉 (just could not resist)

Great x 20 Son of Clippy 2016 mabye. 😉 It's supposed to be gone in the next office but I highly doubt it....Clippy has survived this long.....

It looks like you have no f**ing clue what you're doing. Would you like me to...

• Show you the README, which you should have read in the first place?
• Do it for you? ("It" being formatting your hard drive)
• Call someone to come pick up your computer because you're too dangerous to be using one without supervision?
• Piss off?

I guess that's a bit harsh though...

Though I omitted it, I did read the Readme, and was "leet" enough to find the imgmount command, and all available material before I posted.

Can a floppy image be mounted ISO 9660?
Can a image be automagically decompressed by Dosbox? (Wishlist)
What emulation/copy protection problems will occur. Must it be read-only?
What stratagies are people using to backup old collections?

IMHO, the snippet quoted answers none of these questions. And the info on creating images is devoted to hard drives, which is specifically cited on your wishlist.

I've always heard getting into a flame war with a moderator is fun and profitable. I look forward to the future where I can use my skills to better the community with such questions as, "How do I mount a drive?" "OMG, what's Z:?", and "How do I print?"

Hoping for an intelligent responce, or at least a humourous responce before bannation,

Whoops, there's a -t floppy option. 😵
But nowhere does it talk of how to make the image, and the other questions I asked.

BTW, those comments weren't directed at you TomPaine - I was just taking DosFreak's idea to a terrifying extreme.

I must admit that, not having had a need to deal with floppy images, I am ignorant of DOSBox's features in this area.

DosFreak already suggested you to use an utility called WinImage or any other one for the same purpose.
