If you copy to the current location, you will replace any data there. Used in conjunction with LSEEK and Write of zero bytes, these functions can all be done.

replace:

lseek beginning
copy file
write 0 bytes

append:

lseek end
copy file


replace

lseek (or read destination file to any desired position)
copy file

I know that to replace contents, you must be careful, but it could be done ;-)
