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.

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.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Hash Duplicate Cleaner, simply use the following command:
sudo snap install hash-duplicate-cleaner
Browse and find snaps from the convenience of your desktop using the snap store snap.
