files/
– All uploaded/received files are stored using SHA256 hash as filename. No duplicates, content-addressed.
info/
– JSON metadata for each file: original name, timestamp, size, and most importantly the public key (user identifier).
Every JSON file inside info/ includes a field "public_key" — equivalent to the user who injected the file into the network.
servers.txt
– Plain list of peer nodes. Used by sync.php and discovery routines.
rank.txt
– Generated by meshrank.java: aggregates most frequent public keys & most active servers.
