What is a .logicx file (and how to open one)
Updated July 2026
A .logicx file is a Logic Pro project — and the twist is that it isn't really a file at all. It's a macOS package: a folder that the Finder displays as a single icon. Inside sit the project data and, when the project is saved self-contained, your audio recordings too. That one design decision explains almost everything confusing about the format — why Windows shows it as a plain folder, why you zip it before uploading it anywhere, and why it behaves so differently from Ableton's .als.
What's actually inside a .logicx package
Right-click a .logicx in the Finder and choose Show Package Contents and the illusion drops: you're looking at an ordinary folder. Inside you'll typically find an Alternatives folder — one numbered subfolder per project alternative, each holding a ProjectData file that stores the actual project: regions, MIDI, automation, mixer settings, plugin assignments. Alongside it Logic keeps housekeeping like autosaves and project backups, and — this is the important one — a Media folder for audio that's been copied into the project.
Whether your audio is in there depends on how the project was saved. Logic's save sheet has checkboxes for copying assets — audio files, samples, movie files — into the project. Tick them and the package is self-contained: one icon you can drag to a drive and everything travels. Leave them off and the .logicx merely references audio stored elsewhere on the composer's disk, and opening it on another machine produces missing-file warnings. If you're sending a project to anyone, self-contained is the setting you want.
Why Windows shows a .logicx as a plain folder
Packages are a macOS convention: the Finder agrees to draw certain folders as single files because an app has registered the extension. Windows, Linux and most cloud-drive web interfaces don't play along — they show you what's really there, a directory named Something.logicx full of subfolders. Nothing is broken or corrupted. But it does mean you can't double-click it into anything on a PC, and you can't attach it to an email or drop it into a browser upload as-is. The fix for moving it around is the same everywhere: compress it to a .zip first (right-click → Compress in the Finder), which packs the folder into a genuine single file.
.logicx vs .als — two opposite philosophies
Ableton's .als format is the mirror image. An .als is one real file — gzipped XML — that never contains audio; the samples live beside it in the Live project folder. A .logicx is a folder pretending to be a file, and it can carry its audio inside. So an .als alone is often incomplete, while a self-contained .logicx is the whole project in one object. It also means renaming can never bridge them: changing .logicx to .als just mislabels a folder as a compressed XML document. Ableton will refuse it instantly, because not one byte of the contents is in the right format. Moving a project between the two DAWs means rebuilding it, not renaming it.
How to open a .logicx file
The straightforward answer: Logic Pro opens .logicx files, and Logic Pro runs only on Apple hardware — there is no Windows version. On a Mac with Logic installed, double-click the .logicx (or the .zip someone sent you, after extracting it) and the project opens with all its alternatives, backups and copied-in media intact. If you were sent a folder of loose Alternatives/Media subfolders — usually a package mangled by a cloud drive — keep them together in one folder ending in .logicx and Logic will still treat it as a project.
How to open a .logicx without Logic
No other DAW opens a .logicx natively — it's Apple's own format, and unlike an .als you can't even peek inside with a text editor, because ProjectData is a binary document rather than readable XML. You have two real options.
1. Convert it to an Ableton project. If you work in Live, Doseedo converts the .logicx into a native Ableton .als set — a real, editable Live project, not a folder of stems. Zip the .logicx first (right-click → Compress), then upload the zip. Tracks arrive in order with names and colors; audio clips keep their fades and clip gain; MIDI notes, CC and pitch bend come across; multi-point tempo and time-signature maps, arrangement markers, volume, pan and breakpoint automation lanes, and buses and sends all carry over. On plugins, the honest picture: stock compressor, reverb, and delay settings map to the destination DAW's native devices with their core controls intact; other plugins arrive placed on the right track as device slots to re-fill — third-party preset state isn't reconstructed. It works in both directions (.als → .logicx too); the full spec is on the what-carries-over breakdown.
2. Ask for a bounce or stems. The old way still works: whoever has Logic exports the mix or per-track stems as audio, and you rebuild in your own DAW. You lose the MIDI, automation and editability — which is exactly the gap converting the project is meant to close — but for a quick listen or a remix of frozen parts, stems are fine.
.logicx vs GarageBand's .band
GarageBand saves its own package format, .band, and the relationship between the two is strictly one-way: Logic Pro opens .band projects directly — per Apple's documentation it recreates the GarageBand project's tracks, tempo and key when you open it — but GarageBand cannot open a .logicx. Logic is the superset; a Logic project simply describes things GarageBand has no way to represent. (Logic can share a simplified version of a project to GarageBand for iOS, but that's an export, not opening the .logicx.) If you're the GarageBand user in the exchange, the practical routes are asking for stems — or, if the destination is Live, the GarageBand-to-Ableton path.
Work in Ableton? Convert the .logicx to a native Live set
Zip the .logicx, upload it, and download a real, editable .als — tracks, MIDI, automation, tempo maps and routing rebuilt natively. Free to start — see current plans. Your project uploads over an encrypted connection into a private space only you control — delete it anytime.
FAQ
Can Windows open a .logicx file?
No — Logic Pro only runs on Apple hardware, and no Windows program opens the format. File Explorer shows a .logicx as an ordinary folder, because that's what it is underneath. To work on the project on Windows, convert it to an Ableton .als and open it in Live.
Can Ableton Live open a .logicx file?
Not directly — Live can't read Logic's format. You convert instead: Doseedo rebuilds the .logicx as a native Ableton .als set, with tracks, clips, MIDI, tempo maps, markers, automation and routing carried over.
Why does my .logicx show as a folder?
Because it is one. A .logicx is a macOS package — a folder the Finder displays as a single file. Windows, Linux and many cloud-drive websites don't observe that convention, so they show the folder inside. Nothing is corrupted; keep the contents together and it opens fine in Logic.
Do I zip the .logicx before uploading it?
Yes. Browsers upload files, not folders, so compress the package first: right-click the .logicx in the Finder and choose Compress. The resulting .zip keeps the project data and media together in one uploadable file.
Is the audio inside the .logicx?
It depends how the project was saved. If audio was copied into the project (a self-contained save), your recordings sit inside the package's Media folder. If assets were left referenced, the .logicx only points at audio stored elsewhere — and moving it to another machine breaks those links.
