File locations¶

The data folder¶

Settings ▸ Support ▸ About ▸ Data folder shows the exact path on your computer. The environment variable XOL_HOME, if set, replaces the location; it exists for tests and portable setups.

The program itself is separate: wherever you installed it on Windows, and Xol.app on macOS. Uninstalling the program does not touch the data folder.

Inside the data folder¶

Xol/
├── launcher.json          launcher settings
├── accounts.json          saved sign-ins
├── service.json           an access key saved by an older launcher, if any
├── install-id             random install ID for the online heartbeat
├── playtime.json          last played and total play time per instance
├── instances/             one folder per instance
├── shared/                the server list, options and client settings shared between instances
├── archive/               old 0.2.x instance folders, moved here by 0.3.0
├── migrations/            the record of that move
├── optifine/              Xol's copy of an OptiFine file you added, one folder per Minecraft version
├── versions/              Minecraft and loader versions, and unpacked natives
├── libraries/             shared libraries
├── assets/                shared game assets and Mojang's log configuration
├── runtimes/              Java runtimes from Mojang
│   └── xol-native/        Apple Silicon Macs only: the native Java 8 from Azul
├── cache/                 cached lists and service data
│   ├── service/           accepted remote manifest and remote configuration
│   └── skins/             the faces of signed-in accounts, for the account switcher
├── logs/                  game-<date and time>.log, one per run
└── updates/               verified installers (the last two) and state.json

Do not edit accounts.json or service.json. On Windows their contents are encrypted by the operating system and useless on another computer or user account. On current macOS builds they are not encrypted: they are readable and writable only by your own user account (file mode 0600, data folder 0700), so do not copy them anywhere or share them. See Sign-in and accounts.

Inside an instance¶

Your normal Minecraft folder, which holds the shared resource packs, is %APPDATA%\.minecraft on Windows and ~/Library/Application Support/minecraft on macOS.

The launcher's Open folder menu, on the main screen beside Launch options and in Settings ▸ Instance, opens Mods (your my-mods folder), Resource packs, Screenshots, Saves (worlds), Config, Logs, Crash reports, the Instance folder and the Xol data folder. In Settings it also has Game output logs, the data folder's logs. A standard folder that does not exist yet is created first. See Instances.

Where your things are, by operating system¶

On macOS the Library folder is hidden in Finder. Use Go ▸ Go to Folder… and paste the path, or the launcher's Open folder menu.

The native Apple Silicon runtime¶

On Apple Silicon Macs only. These files are downloaded the first time a game starts with the native runtime; with Intel (Rosetta 2) chosen they never appear. All paths are inside the data folder.

The downloaded Java zip is kept in cache only until it has been unpacked. Deleting runtimes or libraries is safe here too: the files are downloaded and checked again on the next start.

Next to the app on macOS¶

During an update, a hidden folder named .Xol-update-<hex>.app appears next to Xol.app, and after the swap the previous app is kept as .Xol-old-<hex>.app until the next start. Xol removes both itself. See Updates.
