[Coco] Another Coco Virtual Disk Util

[Luis Fernández]

I'm still puzzled about how to do things with modern lenguages 
Although C and C + +, I have not used in years and some do not master the language concepts (classes and some other things,) I understand other polymorphism, recursividas, and others. 
I also know that I could do in VB2010 and there would (perhaps) much difference 
But some things amaze me, his project, and his quick realization, (sorry if I ask), it's just with the idea of ​​learning 
The compression libraries, had to learn how to use them to incorporate in their sources, or you already knew and used previously?, That requires a certain time?. 
The libraries JVC disc formats, MDK, VHD, and the DOS, RSDOS, OS9 and VDK, sources are made by you or am I wrong?, If yours was very fast its implementation, you knew so deep the beforehand? (please do not bother me, it's just curious to know how you should do things) 
I for example take 2 months to understand format MDK, his virtues, the amount of real disks you can handle, consider as physically discs are recorded and each company and model (IBM, PANASONIC, TEAK, etc) FM, MFM and others. I have not yet been implemented, as creating a disc in this format the user could choose 100 parameters. 
The OS9 also presented some doubts about the default sector size for a directory.
THE RSDOS is best known for all but the VDK I had to learn from (zero). 
I was surprised, pleasantly, to find that the VDK has 2 directories (undocumented) Track 16 and Track 20, I guess you already know. 
I had to figure out how to detect the various formats without using the virtual disk extention, this is not standardized. 
I had to learn WAV, and CAS for the converter, PAK to BIN, CART 
Graphics Formats 
Compressed formats, BAS (Tokennized), Decompressing, and DRAGON RSDOS format and as differentiate
I had to use a hexedit of another person. EditPad of Windos and MSPaint, you also implement or are the standard libraries?
I imagine the one-month time delay was used to make the important parts of the application, but you already had much previous knowledge of this? VC2010 even.
Just curious of the history of the application that I do, I find magnificent
It would be very good to know its history.
Congratulations, go ahead
