What file system is for

Understanding Multilogin’s file system helps with troubleshooting, managing logs, and even pre-loading browser extensions. Whether you're digging into logs or customizing profiles, knowing your way around the folders saves time and stress.

➡️ Multilogin stores its local app files in the mlx folder:

Windows: C:\Users\%username%\mlx
macOS: /Users/%username%/mlx
Linux: /home/%username%/mlx

Use this folder to find logs, app components, browser-profile files, custom browser extensions, and exported browser profiles.

File system path

Here’s where to find the main Multilogin folder on your device:

Windows: C:\Users\%username%\mlx
macOS: /Users/%username%/mlx
Linux: /home/%username%/mlx

Important: do not manually move, rename, or delete files inside the mlx folder unless a Multilogin Help guide specifically tells you to. Changing app or browser-profile files can cause startup or data issues.

Folder structure breakdown

FOLDER	PURPOSE
agent	Contains the installed agent version, installation file, and latest log upload info
configs	Stores extra config files for the launcher
custom_extensions	Holds browser extensions you want to pre-upload to profiles
deps	Contains downloaded browser cores
exports	Stores `.zip` files of your exported profiles
launcher (in deps)	Stores versioned subfolders for the agent’s executable
logs	Keeps log files – super helpful for diagnosing issues (and sharing with support)
profiles	Houses profile data, organized by user ID, workspace ID, and profile ID

Pro tips

Pre-upload extensions into the custom_extensions folder for quick use across profiles
Check the logs first when something breaks – send them to support if needed
Profiles folder = the heart of your data. Avoid moving or deleting files inside unless you know what you're doing
