Hash Duplicate Cleaner

Hash Duplicate Cleaner is a fast, accurate Linux desktop utility for finding
and safely cleaning exact and criteria-based duplicate files across multiple
folders. Independent open-source project, not affiliated with or endorsed
by any third-party software vendor.

3-STAGE HASH DEDUPLICATION ENGINE
• Stage 1 (Size Buckets): Immediately skips unique file sizes without reading
unnecessary bytes.
• Stage 2 (Partial Signature): Compares fast head/mid/tail 64 KB blocks
before hashing full files.
• Stage 3 (Full Streaming Digest): Verifies exact duplicates via streaming
SHA-256 or MD5 checksums, with optional Same Name + Same Size mode.

MULTI-FOLDER CRITERIA & PROTECTED FOLDERS
• Scan multiple directories and mark trusted folders as Master / Keep Only
so originals inside protected trees are never selected for removal.
• Filter by minimum and maximum file size or extension presets (All,
Documents, Images, Audio, Archives).

SMART SELECTION ASSISTANT, INLINE PREVIEW & UNDOABLE QUARANTINE
• Inspect grouped duplicates in a color-banded table alongside an inline
text and image preview pane.
• Smart Selection Assistant checks copies automatically with Keep Oldest,
Keep Newest, Keep Shortest Path, and Unmark Protected Folder rules.
• Move selected duplicates to a safe Quarantine backup folder or confirm
permanent deletion, then review history, restore files to their original
paths in one click, or export cleanup reports to CSV.
• Built-in English and Vietnamese language toggle.
