->	1 - Is there a way to do a real move of files?  I would like to

- With one function call, I don't think so, but you should be able to copy
- the file to the destination with a temporary name, delete the old file,
- and then rename the new one with the filename from the old one.  You
- should be able to do all of this, including assigning the temporary name
- (if I'm correct) with INT 21 BIOS calls.

Eeek.  Check Interrupt 0x21, function 0x56, "rename file".  It does
precisely what you want, namely it creates a new directory entry (in the
desired subdirectory) and removes the old entry, without touching the
file itself.  The MSDOS "RENAME" command doesn't make use of this, but
various freely-available programs (often called "mv") do.  Turbo C's
rename() function makes use of this system call.

Naturally it can't work across devices.
