Would you like some help?

You already have code which reads CP/M files, right?  Writing isn't that
much more complex really.  And CP/M allocated new blocks in a quite
simpleminded way: whenever a new block was needed, the first free block
from the beginning of the disk was allocated.  I think it's OK to only
write non-sparse new files to a CP/M disk --- even CP/M's own PIP utility
isn't able to transfer a sparse file from one unit to another....
