No, an IPFS CID does not inherently contain information about its parent folder
. A CID is a unique identifier generated from the content's hash, not its location or its relationship to other files in a folder structure. To find the parent, you would need to retrieve the contents of the folder using its CID and then identify which of those contents, if any, correspond to a known parent directory's CID. Why CIDs don't reveal parent information
- Content-based addressing: IPFS uses content addressing, meaning the CID is derived from the file's content itself, not its location on a server or in a file system.
- Decentralized and distributed: Data is stored across a network of nodes, and a file with the same content will have the same CID regardless of where it's stored.
- Immutable: Any change to the content results in a new, different CID.
- Hierarchical data structure: Directories in IPFS are represented as a Merkle DAG, which is a tree-like structure. While child nodes point to parent DAGs, this structure is defined by the relationships created when the data is added, not by the CIDs themselves.
How to find related information
- Navigate the DAG: To find a parent, you would have to have the CID of the folder you're looking for and then use an IPFS node or gateway to retrieve its contents.
- Use the parent's CID: You can then use the parent folder's CID to look up its contents.
- Use a parent folder's CID: Once you have the parent folder's CID, you can use it to find the parent folder's contents.
