indexes/ folder (Optional)
Purpose: This folder contains additional LevelDB databases for various optional indexes that can be enabled in Bitcoin Core.
txindex/: If you enable txindex=1 in your bitcoin.conf file, this subfolder will store a full index of every transaction ever made, allowing you to look up any transaction by its ID (txid). This takes up significant additional disk space (over 100 GB).
blockfilter/: Stores data for compact block filters (BIP 157/158), used by lightweight clients to query for relevant transactions without downloading the entire blockchain.

bitcoin.conf (optional): This is a plain text configuration file that doesn't exist by default. You can create it in your data directory to customize various Bitcoin Core settings (e.g., prune to save disk space, dbcache for performance, rpcuser, rpcpassword, network settings).

debug.log: A log file that records the albania phone number list activities of your Bitcoin Core client, including connection attempts, errors, warnings, and synchronization progress. It's invaluable for troubleshooting.
peers.dat: Stores information about other nodes (peers) on the Bitcoin network that your client has connected to or knows about. This helps your node quickly re-establish connections.
mempool.dat: Stores unconfirmed transactions that are currently in your node's mempool (memory pool), waiting to be included in a block. This helps your node remember transactions if it shuts down and restarts.
