I am trying to same URL Base for all my uploads on IPFS but if I upload a directory or one file at a time, each of them has a different base, which is then hard to use for a smart contract where I would just change ID and use the same base URL.
How to do it with IPFS I saw projects having URLS like https://ipfs.io/ipfs/QmeSjSinHpPnmXmspMjwiXyN6zS4E9zccariGR3jxcaWtq/9151
where they just change ID at the end, how?
