Read guide →Where your data lives
Launcher settings, profiles, and skin caches live in gr8launcher inside Minecraft’s default directory. Separate game instances live in the Minecraft directory’s instances folder unless a profile points to an existing game folder.
| System | Launcher data |
|---|---|
| Windows | %APPDATA%\.minecraft\gr8launcher |
| Linux | ~/.minecraft/gr8launcher |
| macOS | ~/Library/Application Support/minecraft/gr8launcher |
Back up worlds and instance folders before reinstalling or making large mod changes. Ely.by credentials use native credential storage when available, with a session-only fallback.
Launcher updates
Use Options → Updates to check published versions and release notes. Download the correct package from Downloads when updating manually.
