Your files, organized while you sleep.
Dolfer is a lightweight desktop app that automatically tidies your Downloads, Photos, and project folders using simple “when X happens, do Y” rules — so you never sort a folder by hand again.

Clean — Dolfer keeps it that way.
It’s live — flip the switch, swap a type, or tap a file. Not a screenshot.
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, dimensions, location, 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
Dolfer runs natively on Windows, macOS, and Linux — the same app and the same rules on each, used on the devices your license covers.

How it works
From messy to managed in three steps
Pick your folders
Point Dolfer at the folders you want kept tidy — Downloads, Desktop, Photos, a project directory, anywhere.
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.
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.

Debian / Ubuntu / Mint / Pop — the .deb installs with a double-click (app-menu entry) and auto-updates via apt; installing it wires up the repo for you.
Any other distro — the AppImage runs anywhere and auto-updates in-app; make it executable first:
chmod +x Dolfer-x64.AppImage && ./Dolfer-x64.AppImage
macOS builds are Apple-signed and notarized. The Windows installer isn't code-signed yet — on first launch SmartScreen may prompt; click More info → Run anyway.

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. Your license isn't tied to a platform — the same key activates on whichever OS you install.
Can I try it before buying?
Yes — every install starts with a free 7-day trial of the full app, no account or card required. Build real rules and let Dolfer organize your actual files, then buy a license whenever you're ready — the same install unlocks instantly.
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. Updates are included for the period shown on your plan, and you can renew anytime to extend; the app keeps working either way. Buy once and it's yours to keep.
Is my license tied to one computer?
Each activation is tied to your computer's hardware, not its operating system — so you stay covered through changes to the same machine. Reinstall Windows, or even switch that same computer from Windows to Linux, and your license keeps working automatically; re-activating the same hardware never uses up an extra slot. A different physical computer is a separate activation, though: every plan covers a set number of computers (1, 2, or 3), so adding a brand-new device beyond that needs another license. Replacing an old machine? Deactivate the license on it first to free the slot, then activate on the new one.
Do I keep the app — and what happens after the year of updates?
Yes, it's yours to keep. Dolfer is a one-time purchase, never a subscription, so the app keeps working forever. Your purchase includes one year of updates — every new feature and improvement we ship that year is yours. After the year, nothing changes about the app you already have: it keeps running exactly as-is, you simply stop receiving new features. Bug fixes are the exception — we still address reported bugs so your version stays reliable. You can renew anytime for another year of new features, but you're never required to.
