File Management

When to Use

You need to reorganize a directory (move/copy/rename) based on include/exclude patterns and a target folder structure.
You want a repeatable backup workflow (copy or archive) with optional retention rules and verification manifests.
You need to compress a folder or a set of files to reduce size or package deliverables.
You must split very large files into fixed-size parts for transfer/storage limits (binary-safe).
You need to merge previously split parts back into the original file reliably (binary-safe).

Safety-first planning: generate a preview/manifest of intended actions before writing changes.
Rule-driven scope control: root path + include/exclude patterns + thresholds + target structure (see references/rule-schema.md).
Conflict handling: default to skip/rename on collisions; overwrite only with explicit confirmation.
Non-destructive defaults: avoid deletion unless explicitly requested.
Verification support: compare counts/sizes and optionally generate hashes for critical backups.
Binary-safe split/merge: split by fixed size and merge parts without corrupting binary data (scripts/).
