I found the "new" EmuDisk. From the author:

Making progress. EmuDisk rebuild now supports JVC, VDK, DMK, OS9 (raw), and 
VHD images (needs more work to include partition selection); RSDOS, OS9, 
DragonDos formats.

Display of directories is complete.

Still much more to go.

My final project is a bit eccentric, but available to check out if anyone is 
interested. I have shared it on github (https://github.com/wzydhek/EmuDisk). 
This project is being written in C++ using Microsoft Foundation Classes 
(MFC) in Visual Studio 2015. I say eccentric, because very few people (if 
any) would ever make use of this application. Let me explain...

I grew up in the 80's and what got me interested in computers to begin with 
was the Tandy Color Computer, also called a CoCo (Similar to a Commodore 64 
or a TI-99/4A). I've never lost interest in that old machine. And although I 
no longer have one, I DO use an emulator called M.E.S.S. 
(http://www.mess.org/) to emulate the CoCo.

In the emulation, I can use virtual floppy disks containing programs and 
data for the emulated machines. Now, the tricky part, and the reason for 
this project, is the ability to transfer data between the virtual disks, and 
my host operating system (Windows). There IS a command line utility and a 
very simple GUI application to handle this already, both are a pain to use 
for the most part, and there is a lot of improvements that could be made.

So, several years ago, I delved into writing a usable utility from scratch. 
I wrote it in C#. And although I am not a complete novice at writing code, I 
had MUCH to learn at that point and have done so since. The application was 
useful and MUCH improved over what was previously available, but it was 
still lacking some features I wanted to implement. I did share the utility, 
and received some feedback on it (some suggestions for improvement, as well 
as a few bug indications).

So, fast forward to the present. After taking this class, I decided to make 
my final project a re-write of the application in C++ with MFC. Up until 
recently, my experience with C++ was sparse to say the least, but at least 
enough to get my feet wet.

Now I have a basic skeleton of an application with the beginnings of some 
functionality. It still supports multiple disk image formats (VDK, DMK, OS9, 
JVC, VHD) as well as operating system formats that reside on them (RSDOS, 
CoCo OS-9). In addition I have added support for the DragonDos operating 
system format (which was missing from my earlier application).

I have structured the code so that I can add additional virtual disk image 
formats, as well as additional operating system formats in time.

So far, the application can open and view the contents of such virtual 
disks, create new blank disks, and save the virtual disks. Next to come are 
drag-n-drop and import/export files to/from my host system as well as nice 
little features such as hex sector editor, file viewer (supporting a variety 
of file types from those operating systems), boot sector 
import/export/creation and whatever else comes to mind.

If anyone is interested in playing with this utility, keep in mind you will 
need virtual disks to work with. There are many scattered over the internet. 
Of course the virtual disks won't do you any good without an emulator to use 
them in, such as M.E.S.S, VCC (http://www.coco4.com/vcc/ - CoCo emulation), 
or XRoar (http://www.6809.org.uk/xroar/ - Dragon & CoCo emulator).

Any questions about any of these, please feel free to hit me up.

Or if you'd just like to clone a copy of my code just to see an example of 
C++ with MFC coding, feel free to visit the my project on github.
