Use the ANSI-standard function `rename'.  It's part of DJGPP library.

`rename' will use whatever appropriate (long file name function when long 
names are supported, short names otherwise).  I don't see how this should 
be of any concern to the application.

But it's the only way to go when you need to move a file to another 
disk.  So if moving files to another disk is required, you will need to 
watch the status returned by `rename', and if it indicates a failure, use 
the copy/delete thing instead.
