Features

Automation that actually feels effortless

Powerful enough for power users, simple enough that you'll set it up once and forget it exists.

Set-and-forget automation

A tiny background service lives in your system tray and runs your rules the instant something changes. Configure it once; it works around the clock.

Visual rule builder

Compose triggers + conditions + actions with clicks — no code. Match by name, type, size, date, contents, or duplicates, with nested AND/OR groups.

Completely reversible

Every action has full undo, and a dry-run preview shows you exactly what will happen before a single file moves. Mistakes are impossible to keep.

Private & offline

Everything runs locally on your machine. No cloud, no uploads, no telemetry. Your files never leave your computer — internet is only needed to purchase.

Native speed

Built in Rust with a tiny memory and CPU footprint. It responds instantly and stays out of your way — you'll forget it's even running.

Truly cross-platform

One license, every desktop. Dolfer runs natively on Windows, macOS, and Linux with the same clean experience everywhere.

How it works

From messy to managed in three steps

1

Pick your folders

Point Dolfer at the folders you want kept tidy — Downloads, Desktop, Photos, a project directory, anywhere.

2

Build a rule

Use the visual builder to say “when a file is added, if it's an image, move it to Photos/{year}/{month}.” Preview it with a dry run.

3

Let it run

Dolfer watches in the background and applies your rules instantly, forever. Your folders simply stay organized.

Use cases

A few of the things people automate

Downloads, auto-sorted

New downloads are filed by type into their own folders the moment they land. No more 400-item Downloads graveyard.

Photos filed by date

Every photo automatically lands in Photos/{year}/{month} — a clean, browsable archive that builds itself.

Screenshots tamed

Screenshots get renamed to something meaningful and moved out of the way the instant you take them.

Old files archived

On a schedule, anything older than 30 days is swept into an archive folder — keeping your active space lean.

FAQ

Questions, answered

Is it safe? Can I undo changes?

Yes. Every action Dolfer takes is fully reversible with one-click undo, and you can run any rule as a dry-run preview to see exactly what would happen before anything moves. Nothing is ever deleted without your say-so.

Does it work offline?

Completely. Dolfer runs entirely on your machine — no cloud, no uploads, no telemetry. Your files never leave your computer. An internet connection is only needed once, to complete your purchase and activate your license.

Which operating systems are supported?

Dolfer is natively cross-platform and runs on Windows, macOS, and Linux. The same license works across platforms, so you can move between machines freely.

Can I try it before buying?

Yes — the dry-run preview lets you build and test rules and see precisely what they would do before committing, so you always know what you're getting. A purchased license unlocks unrestricted, ongoing automation.

What does a license cover?

A license is a one-time purchase that unlocks every feature on the number of computers in your tier (1, 2, or 3 users) — with no subscription and free updates for life. Buy once and it's yours to keep.
