DiffSeeker

DiffSeeker scans directory trees, records file metadata plus content hashes, and supports cross-volume comparison for:

• duplicates (same hash + size) across volumes
• missing files (present on one volume, absent on others by hash+size)
• suspicious divergences (same name, different size)

Python CLI (mpchunkcfa compatible)

Install (editable dev install):

pip install -e .

Scan a directory and emit CSV:

mpchunkcfa --walk /path/to/root -V "VOL_A" -c vol_a.csv

Scan and ingest into SQLite:

mpchunkcfa --walk /path/to/root -V "VOL_A" --db diffseeker.db

Exclude directory elements (repeatable):

mpchunkcfa --walk . -V "VOL_A" --exclude .git --exclude .svn

Data model

Each file record includes: name, relative_path, extension, size, creation_date, modified_date, hash_value, file_type, number_of_files, volume_name.

5) Notes on compatibility and correctness

• Your earlier runtime error (root undefined in worker) is eliminated by passing root and directory into _compute_record.
• The exclusion logic is path-element based, so .gitignore is not excluded when excluding .git.
• creation_date is OS-dependent semantics (ctime on Unix). If you later want “birth time” portability, we can normalize explicitly per platform.
