[Visual D] Would it be easy to support accurate project cleaning?

You could simply add a batch file that copies all the data files 
after the post build. If the files are large, it would be slow 
and not work.

Alternatively, you could move pre-build and move back post-build 
for speed. This, of course, assumes the files are rather static, 
which they probably are.

Obviously not optimal but might work in your scenario.
