As far as I understand, `ipfs repo gc` removes all blocks, except those that are pinned and/or added by ipfs files api (these are best-effort pinned, according comments on [this](https://github.com/ipfs-inactive/faq/issues/143#issuecomment-231484012) and [this](https://github.com/ipfs/go-ipfs/issues/4675#issuecomment-364302071)) However, even after unpinning all pins, and running ipfs files rm on all files, I still had this one cid locally - `QmUNLLsPACCz1vLxQVkXqqLX5R1X345qqfHbsf67hvA3Nn`. I was able to verify that its present locally both by checking the output of `ipfs refs local`, and by checking the `$IPFS_PATH/blocks` for the base32 multihash of the cid - `ciqftfeehedf6klbt32bfaglxezl4uwfnwm4lftlmxqbcerz6cmlx3y`. This cid seems to be the cid for an empty directory, and I’m not sure how its not getting cleaned up by `ipfs repo gc`…? ---

Because having nothing stored in MFS (files-api) is equivalent to having an empty folder. So the CID for the empty folder is always there.
