What dskDitto is
dskDitto finds duplicate files across disks with parallel scanning and offers a terminal interface by default plus an optional, experimental graphical interface. It checks file contents with SHA-256 by default, with BLAKE3 available, and includes exact filename matching and fuzzy content similarity for finding near-matches. Fuzzy mode uses a default 75% similarity threshold and disables automatic remove and link actions. Scan filters cover size, depth, hidden files, symlinks, virtual filesystems, and filesystem boundaries. Users can preview files, exclude folders, choose files automatically, and export results as CSV, JSON, or plain text. Files are not deleted or rewritten unless the user explicitly requests it with the remove option; that action can delete extra copies or replace them with symlinks or reflinks. Reflink conversion requires a supported copy-on-write filesystem, such as APFS, Btrfs, or XFS with reflink enabled. The default source installation builds the CLI and TUI; the GUI is optional. Source installation requires Go 1.22 or later, while GUI builds also require Raylib and CGo. The project is released under the Apache license.
Good
- Uses parallel processing to scan for duplicates
- Supports SHA-256 and optional BLAKE3 verification
- Offers filters for size, depth, and filesystem details
- Does not alter files without an explicit remove request
Watch out
- Graphical interface is optional and experimental
- Default installation builds only the CLI and TUI
- Reflink conversion needs a supported copy-on-write filesystem
Who it suits
dskDitto suits Linux and macOS users who want to locate duplicates from a terminal or try an experimental graphical interface. It may also fit users who need file previews, configurable scan filters, and exportable results.
Verdict
dskDitto offers detailed scan controls and several ways to review or export duplicate results. The default setup is terminal-based, and its optional GUI and reflink actions have additional requirements.
