Database schema

The default index file is .nefaxer in the indexed directory (override with -d / db_path). SQLite runs in WAL mode.

Tables

CREATE TABLE paths (
    path TEXT PRIMARY KEY,
    mtime_ns INTEGER NOT NULL,
    size INTEGER NOT NULL,
    hash BLOB
);

CREATE TABLE diskinfo (
    root_path TEXT PRIMARY KEY,
    data TEXT NOT NULL
);

paths

Column	Description
path	Relative path from indexed root (primary key)
mtime_ns	Modification time in nanoseconds
size	File size in bytes
hash	Optional 32-byte Blake3 digest when hashing enabled

diskinfo

Stores drive-detection / tuning metadata for the indexed root (root_path + JSON data).

Library mapping

In Rust, a snapshot is Nefax = HashMap<PathBuf, PathMeta> with the same fields as paths. See Library and docs.rs/nefaxer.

Encryption

With --encrypt / encrypt = true, the file is a SQLCipher database. Passphrase handling is described in Configuration.
