Please clarify your meaning (in terminology). By files, do you mean in RAM or on disk? Both meanings are possible in programming terminology.

To release a sage/python object still in scope, call del(objname).
If you want to delete a disk file, you can find it under the "~/.sage/" directory on unix-like systems.

Thank you: del does the trick. A pitty that del? does not give a hint in sage....

The reason is that del is a keyword statement in python, not a first-class object (not everything is an object in python):
