What dskDitto is

dskDitto helps find duplicate files on Linux and macOS through a terminal interface, with an optional graphical interface. It scans local paths and directories using parallel processing, and can include virtual filesystem directories when enabled. Content checks use SHA-256 by default, with BLAKE3 available as an alternative. The tool also supports exact filename matching and fuzzy content similarity for near-duplicate searches; fuzzy mode starts at a 75% similarity threshold and turns off automatic removal and link actions.

Scans can be filtered by file size, directory depth, hidden files, symlinks, virtual filesystems, and filesystem boundaries. Users can preview files, exclude folders, use automatic selection, and export results to CSV, JSON, or plain text. Deleting extra copies or replacing them with symlinks or reflinks requires an explicit remove option. Reflink conversion depends on a supported copy-on-write filesystem, such as APFS, Btrfs, or XFS with reflink enabled.

The default installation builds the command-line and interactive terminal interfaces. The optional Raylib graphical interface is experimental. Source installation requires Go 1.22 or later; GUI builds also require Raylib and CGo. The project is free and released under the Apache license.

Who it suits

dskDitto suits Linux and macOS users who want to locate exact duplicates or content-based near matches across local directories. It offers terminal workflows by default, with an experimental graphical option and exportable results.

What it does well

Parallel scanning searches local paths and directories.
SHA-256 is the default, with BLAKE3 as an option.
Filters cover size, depth, hidden files, symlinks, and filesystems.
Results export to CSV, JSON, or plain text.
Files are changed only when removal is explicitly requested.

What to know first

The Raylib graphical interface is experimental and optional.
Reflink conversion requires a supported copy-on-write filesystem.
Source installation requires Go 1.22 or later.

Getting started

Install from source using Go 1.22 or later.
Build the default CLI and TUI, or add Raylib and CGo for the optional GUI.
Choose local filesystem paths or directories to scan.
Set scan filters and choose hashing or matching options.
Review results, then export them or explicitly request removal or link actions.

Verdict

Choose dskDitto if you want configurable duplicate and near-duplicate searches from a terminal, with export and explicit file-action controls. Look elsewhere if you need a mature graphical interface.

Questions

How much does dskDitto cost?

It is listed as free.

Which platforms does it support?

The listed platforms are Linux and macOS.

Does it have a graphical interface?

Yes, an optional experimental Raylib GUI is available. The default installation builds the CLI and TUI.

How does it identify duplicates?

It supports SHA-256, BLAKE3, exact filename matching, and fuzzy content similarity. Fuzzy mode defaults to a 75% similarity threshold.

Can it delete files automatically?

The tool does not delete or rewrite files unless removal is explicitly requested. Fuzzy mode disables automatic remove and link actions.

What does reflink conversion require?

It requires a supported copy-on-write filesystem; named examples are APFS, Btrfs, and XFS with reflink enabled.
