- rutern relative only
- Have accept absulet path on listing
Tests needed:
- Fail if cache_dir from previous run cannot be deleted
- Fail if cache_dir cannot be created from current out_dir
- transfer_type_explorers: Explorers are not transferred twice
- transfer_type_explorers: No transfer tried if there are no type_explorers
