Hi, I’m wondering how you can get the hashes for stuff you’ve added before, but did not pin. Ie. uploading stuff to get the hash (and potentially retrieve it when there’s the same file in the network in the future) and then clearing cache to save space. Do I have to manually copy the hashes from ipfs refs local ? or is there a log of everything I’ve added.
