Awesome workspace file management.

I’ve tried multiple alternatives before, but they always fell short. Fileside changes that completely.


Make Tech Easier

The paradigm of switching between sets of panes is brilliant.

Why Fileside?


Reduce cognitive load

Fileside tackles the ongoing challenge of recalling where you saved things and repeatedly navigating to those locations.

Mise en place

Just like a chef sets up their kitchen before cooking a meal, Fileside lets you set up your folder workspace for each project. But unlike the chef, you only need to do it once. No more opening multiple windows, navigating to the right place in each one, then painstakingly resizing and arranging them side-by-side just to start moving files around.

Keep things local

Fileside champions a local-first approach. Instead of storing everything in the cloud (a.k.a. other people's computers), it helps you turn your local drives into a versatile storage environment.

Embrace the file system

In recent years, there's been a trend towards hiding the underlying file system from the user in a misguided attempt at user-friendliness. Fileside takes a transparent approach, and lets you work with the file system exactly as it is.

Designed for the desktop

Fileside is designed to run on a computer, not on a tablet or a phone. It works the same way across Mac and Windows, helping you keep your workflow consistent and your sanity intact.

No recommendations

And last but not least, Fileside will never start pushing recommended content in front of you. You're in charge.

What users say


The last file manager you will ever need.

I bought your app on Black Friday together with five other programs, but yours is the only one that survived serious testing and stayed in my workflow. I'm a new fan, but I use it every single day.

It's a genius product that is fun to use.

Before finding your product I actually hired people to create a similar program for daily use at the office. In the middle of the journey I found Fileside, which was exactly what I needed.

Definitely the only Finder replacement that's ever needed.

Just want to call out how much I enjoy Fileside search. Zero bullshit. No gimmicks.

Fileside feels very lightweight.

Being able to save specific combinations of multiple panels and reopen them with one click completely changed how I organize my work.

Fileside seems to me like a full-fledged NC/TC replacement (and more) for both Mac and Win!

As a consultant, the ability to create workspaces for each client was a game-changer.

Fileside has transformed how our non-profit manages files! The pane-switching feature is brilliant, and the file/folder organization is incredibly intuitive. Finally, a tool that simplifies complex structures.

I like the transparent, no-nonsense design (it shows the real filesystem instead of hiding it), and that one license covers both my Mac and Windows machines.

You have created an invaluable app!

This is my opinion, but of all the dual-pane (or multi-pane) file managers available on macOS this is by far my favorite.

My favourite feature is the workspaces - I work with different "identities" for different clients (as well as having things I do just for fun). I just sent an invoice out to a client, which involves moving the file from "downloads" to "invoices" - and it was such a delight to just click on the "Accounting" workspace, and drag the file between the two relevant panes. Wonderful!

I absolutely love some of the concepts you've brought to the table. The paradigm of switching between sets of panes is brilliant and the sort of feature I hope to see become mainstream.

World-class support from the developer.

I have tried hundreds of file managers and Fileside is definitively top class. I'm debating between it and File Pilot (which I know is pretty different in several areas) and I feel like Fileside aligns more with what I want (and have been trying to find for a long time).

I wish I had known about this great file manager a little sooner.

This is a really unique app. Having workspaces and any number of frames is just great.

Just tried Fileside, and it's AWESOME.

I really enjoy Fileside, it's the only thing like it and really smooths my workflows and de-clutters my desktop.

High performance, excellent design and quick/easy.

It really looks like it might be the file manager I've been searching for. I used Path Finder for years before I gave up in disgust, then Forklift for years as well until again I gave up.

All things considered, Fileside is an excellent program.

Architecting a desktop app in 2026

This article is about applying classic software architecture principles to Fileside, a modern desktop app built with Electron, TypeScript and React. We’ll be talking mostly about the high-level structure, and how to leverage ideas from the Hexagonal, Onion, Clean, Explicit and Domain-Driven architectural styles.

Introducing Fileside 2

It’s done. It took a bit longer than I’d hoped but Fileside 2 is done. It represents an almost complete rewrite and features a new thumbnail grid, a completely reworked layout management system, non-blocking file transfers, tons of new settings and much more.

The plan for Fileside 2

Over the past year I’ve had a steady stream of emails asking if a Fileside version 2 is coming. One even wondered whether the project is still being maintained. The short answer is yes. Fileside 2.0 is deep in…

Four weeks of voice computing - here's what I learnt

After a recent flare-up of RSI-related wrist pain, I decided to make a serious attempt at becoming proficient at speech computing. My hope was to be able to add an alternative input method in order to offload my hands, and allow them some rest even during my daily work. I’m now four weeks in and this post summarises my impressions. The journey has had its fair share of frustrations, but also brought some surprising insights.
