I don't know of a way to actually make the file transfer conditional.  But 
if you're running your jobs inside a DAG, you could use a POST script to 
get rid of the undesired files -- so you wouldn't save file transfer 
bandwidth, but you at least wouldn't have to deal with the files manually.
A POST script can know the return code of the job, so it would be easy to 
delete the error file if the job succeeded...
