clear sql server replication files

We're doing a full backup of each of our production databases every night.

We also have an hour replication occuring during the day to a report database.

It looks like the unc share ran out of space today. Is there an automated delete feature for the replication files? Or do I need to manually delete the replication folders that I no longer need to preserve?

From stackoverflow

• From my experience, You just need to clean up some space to make sure there is enough space for UNC share. Then start the replication again.
