[Coco] Another Coco Virtual Disk Util

[Walt Zydhek]

Modified Drag and Drop behavior so that dropped files will not be duplicated
if dropped on same disk. You can now drag the root directory to copy the
entire disk contents without creating a subdirectory the name of the source
disk if the destination is another virtual disk. Improved RSDOS format
detection. Also added an Import File progress dialog. Now supporting 0
length files in OS9 Formats. Added logic to determine if there is enough
space on the destination for a dropped file.

It would be difficult at best to drag multiple directories at once. The
TreeView only allows a single node to be selected. If multiple Nodes were
selected it would cause problems for the ListView.
I may keep this in mind for the future though.

One thing I have noticed though, for dragging files from a source that has a
LOT of content, the cursor doesn't change immediately indicating a drag
operation is in progress. This is because of the logic I used to make drag
drop work for both Windows and Virtual Disks. In this case, when a drag
operation is initiated, all recursively selected files are read and buffered
in preparation for dropping. This buffering process can take a bit on disks
with a LOT of content. The only way around this is to only buffer the
selected files or nodes, and then do the recursion in the drop handler. That
in itself could be problematic. I would rather wait on that until I can find
someone more experienced with C# coding to assist me.

I downloaded the latest version this morning. I have not tried the instance
setup yet. The format error is now gone, but a different error occurred
which I have not been able to reproduce. It occurred when I was copying a
large directory with multiple subdirectories. It did not copy them, and I
ended up making the parent dir and copying the subdirs one at a time. I
don't know how difficult it would be, but can you make it so when copying
larger dirs it gives you some impression that it's working? I sat here for a
minute with no change to the screen before I started checking to see what
was happening. I closed the image and reopened it before I was sure the dir
didn't copy.

I also noticed if you drop a dir after you started to drag it, and you drop
it in the same image, EmuDisk will just create a new copy of the whole dir.
I think a confirmation dialog would be handy to avoid having to delete dirs
created unintentionally..

A new thing showed up after I formatted an image with EmuDisk. When I went
to open it again after closing it, I was for the first time asked which OS I
wanted to open it under because it was formatted both. I never selected
RSDOS in the format, and there was no BOTH option, so I don't know what is
happening there. It made me think it might be better to give someone the
option of setting up partitions for OS9 and RSDOS so that this won't happen
unless the user specifically requests it through a dialog.

The most difficult suggestion/request in this post, can you make it so I can
select multiple dirs to drag? I can only copy one at a time, and it would be
faster to be able to select the dirs I want to copy and copy them all at
once.

Thanks for all the work you are doing on this, Walt. EmuDisk is proving to
be the file-copy program I need for copying between vhd images.
