File Deduplicator

• You have large document, photo, or download folders that have accumulated duplicate files over time and want to reclaim disk space.
• You manage project directories and need to identify redundant source files or build artifacts across multiple locations.
• You want to audit and clean up backup drives without permanently deleting anything (archive mode keeps files recoverable).
• You need a safe, preview-first workflow — dry-run mode shows exactly what would be removed before any action is taken.

• You need to detect near-duplicate images by visual similarity (image similarity detection is listed as a future roadmap item, not currently supported).
• You need to deduplicate files stored on cloud services like S3 or Google Drive (network and cloud drive support is not yet implemented).
• You need automated scheduled scans (scheduling is on the roadmap but not currently available).

Identifies exact duplicate files by comparing their content rather than just names or sizes. This means renamed copies of the same file are still detected, making it the most reliable method for documents and code.

Choose between content hashing (most accurate), size-based comparison (fastest), or name-similarity detection (good for finding versioned files like file_v1, file_v2). Each method suits different use cases and performance needs.

Run any scan or removal operation in dry-run mode to see exactly which files would be affected before committing to any changes. Ideal for verifying results on unfamiliar directories.

Rather than permanently deleting duplicates, move them to a configurable archive folder. Files remain fully recoverable, and all moves are logged for audit and undo reference.

Set a size threshold so files above a certain size (default: 10MB) are never automatically removed. Whitelist critical directories to ensure they are never scanned or modified.

Each scan returns duplicate counts, total files scanned, bytes wasted, potential space savings, and scan duration. A log file records every action taken for recovery and audit purposes.

Scan accumulated photo libraries and download folders to surface duplicate images, installers, and media files. Keep the newest copy and delete or archive the rest to recover gigabytes of space.

Find duplicate PDFs, Word documents, and reports spread across multiple folders. Archive older versions and keep the latest, preventing version confusion and reducing backup size.

Identify duplicate source files and build artifacts across project directories. Exclude node_modules and .git automatically, then clean up what remains to keep repositories lean.

Analyze backup drives for redundant copies of the same files. Use the space savings estimate to understand how much storage is being wasted before committing to any removals.
