Binary Duplicate Finder is a fast, deterministic Linux desktop utility for verifying exact binary duplicates byte-by-byte and detecting near-duplicate filenames across multiple folders. Independent open-source project, not affiliated with or endorsed by any third-party software vendor.
BYTE-BY-BYTE BINARY COMPARE ENGINE • Verifies exact duplicates through a 3-tier binary check: Exact Size bucket -> 4 KB Head + Tail signature -> Chunked Byte-for-Byte stream comparison. • Live telemetry displays scan throughput (MB/s), total files scanned, duplicate groups, and reclaimable bytes.
FILENAME SIMILARITY & HEX DIFF INSPECTOR • Optional SequenceMatcher filename similarity mode (adjustable 50% to 100% threshold) surfaces near-duplicate revisions and versioned documents. • Side-by-side inline inspector previews text, images, and hexadecimal byte dumps with highlighted first-64-byte binary differences between pairs.
SMART AUTO-CHECK, MOVE/DELETE & SCAN PROFILES • Auto-check copies with Keep Oldest, Keep Newest, or Keep Smallest Folder rules, then safely Move Checked to Folder or confirm deletion. • Save exclusion folder patterns, size bounds, similarity presets, and JSON scan history across sessions, with English and Vietnamese interface support.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Binary Duplicate Finder, simply use the following command:
sudo snap install binary-dup-finder
Browse and find snaps from the convenience of your desktop using the snap store snap.
