The An Anime Game Launcher uses several directories to store game files, configurations, and cached data. Understanding these paths helps with troubleshooting, backups, and disk space management.

​
Default Directory Structure

All launcher and game files are stored under the launcher folder: 
~/.local/share/anime-game-launcher/
This location follows the XDG Base Directory specification for Linux applications.

​
Primary Directories

​
Launcher Folder

​
LAUNCHER_FOLDER
path
default:"~/.local/share/anime-game-launcher"
Main launcher directory containing all launcher-specific files.This is the root directory for all launcher data, configurations, and game installations.
Contents: 
~/.local/share/anime-game-launcher/
├── config.json          # Launcher configuration
├── debug.log            # Debug and error logs
├── background           # Launcher background image
├── .first-run          # First-run marker file
├── .keep-background    # Preserve background marker
├── game/               # Game files directory
└── components/         # Downloadable components

​
Cache Folder

​
CACHE_FOLDER
path
default:"~/.cache/anime-game-launcher"
Temporary cache directory for launcher.Contains processed images, temporary downloads, and other cache data. Safe to delete if launcher is closed.

~/.cache/anime-game-launcher/
└── background          # Processed background image

​
Game Directories

​
Game Installation

​
game.path
path
Game installation directory.This path varies based on selected game edition (Global or China).
Default locations:
  • Global Edition: ~/.local/share/anime-game-launcher/game/global/
  • China Edition: ~/.local/share/anime-game-launcher/game/china/
Game directory structure: 
~/.local/share/anime-game-launcher/game/global/
├── GenshinImpact_Data/    # Game data files
├── GenshinImpact.exe      # Game executable
├── UnityPlayer.dll        # Unity engine
├── pkg_version           # Version information
└── Audio_*_pkg_version   # Voice package versions

​
Wine Prefix

​
game.wine.prefix
path
Wine prefix (Windows environment) directory.Contains Wine’s virtual Windows filesystem including registry, system files, and installed Windows components.
Wine prefix structure: 
~/.local/share/anime-game-launcher/game/wine-prefix/
├── drive_c/              # Virtual C: drive
│   ├── windows/         # Windows system files
│   │   ├── system32/   # DXVK DLLs installed here
│   │   └── syswow64/   # 32-bit system files
│   ├── users/          # User profiles
│   └── Program Files/  # Program installations
├── dosdevices/          # Drive letter mappings
└── user.reg            # User registry hive
The Wine prefix can become quite large (1-2 GB). Do not delete while game is running or launcher is open.

​
Wine Builds

​
game.wine.builds
path
default:"~/.local/share/anime-game-launcher/game/wine"
Downloaded Wine versions storage.Each Wine build is extracted to a subdirectory named after the version.
Wine builds structure: 
~/.local/share/anime-game-launcher/game/wine/
├── wine-ge-8-25/        # Wine-GE version
├── lutris-7.2/          # Lutris Wine version
└── proton-ge-8-32/      # Proton-GE version
Average size: 200-500 MB per Wine build

​
DXVK Builds

​
game.dxvk.builds
path
default:"~/.local/share/anime-game-launcher/game/dxvk"
Downloaded DXVK versions storage.
DXVK builds structure: 
~/.local/share/anime-game-launcher/game/dxvk/

Game updates can require additional temporary space (up to 20 GB during major updates).

​
Cleaning Up Space

​
Safe to Delete

When launcher is closed: 
# Clear cache
rm -rf ~/.cache/anime-game-launcher/*

# Remove old Wine builds (keep current version)
rm -rf ~/.local/share/anime-game-launcher/game/wine/wine-ge-old-version

# Remove unused DXVK builds
rm -rf ~/.local/share/anime-game-launcher/game/dxvk/dxvk-old-version

# Remove old sessions
rm -rf ~/.local/share/anime-game-launcher/game/sessions/unused-session

​
Do Not Delete

While launcher or game is running:
  • Wine prefix (wine-prefix/)
  • Current Wine build
  • Current DXVK build
  • Game installation (game/global/ or game/china/)
  • config.json

​
Backup and Migration

​
Backing Up Game

Complete backup: 
tar -czf anime-game-backup.tar.gz ~/.local/share/anime-game-launcher
Game files only: 
tar -czf game-only-backup.tar.gz ~/.local/share/anime-game-launcher/game/global
Configuration only: 
cp ~/.local/share/anime-game-launcher/config.json ~/config-backup.json

​
Restoring from Backup

# Extract complete backup
tar -xzf anime-game-backup.tar.gz -C ~/

# Restore configuration
cp ~/config-backup.json ~/.local/share/anime-game-launcher/config.json

​
Moving to Different Location

To move the launcher to a different directory:
  1. Close launcher completely
  2. Move directory: mv ~/.local/share/anime-game-launcher /new/location/
  3. Create symlink: ln -s /new/location/anime-game-launcher ~/.local/share/anime-game-launcher
  4. Restart launcher
Symlinking allows moving game to different partition (e.g., larger drive) while maintaining standard paths.

​
Permissions

​
Required Permissions

All launcher directories should be owned by your user with read/write permissions: 
# Check ownership
ls -la ~/.local/share/anime-game-launcher

# Fix permissions if needed
chown -R $USER:$USER ~/.local/share/anime-game-launcher
chmod -R u+rw ~/.local/share/anime-game-launcher

​
Common Permission Issues

Error: Cannot write to prefix 
chmod -R u+rw ~/.local/share/anime-game-launcher/game/wine-prefix
Error: Cannot update config 
chmod u+w ~/.local/share/anime-game-launcher/config.json

​
Custom Paths

While the launcher uses standard paths, you can customize locations through configuration:

​
Changing Game Path

Edit config.json: 
{
  "game": {
    "path": "/custom/path/to/game"
  }
}

​
Changing Wine Prefix

{
  "game": {
    "wine": {
      "prefix": "/custom/path/to/wine-prefix"
    }
  }
}
Custom paths must have proper permissions and sufficient disk space. Absolute paths are required.

​
Troubleshooting Path Issues

​
Launcher Can’t Find Game

  1. Verify game path in config.json
  2. Check directory exists: ls -la ~/.local/share/anime-game-launcher/game/global
  3. Verify GenshinImpact.exe exists in game directory
  4. Check file permissions

​
Wine Prefix Errors

  1. Verify prefix path in configuration
  2. Check prefix isn’t corrupted: 
    ls ~/.local/share/anime-game-launcher/game/wine-prefix/drive_c
  3. Regenerate prefix by deleting and restarting launcher: 
    rm -rf ~/.local/share/anime-game-launcher/game/wine-prefix

​
Out of Disk Space

  1. Check available space: 
    df -h ~/.local/share/anime-game-launcher
  2. Clean up old Wine/DXVK versions
  3. Remove unused sessions
  4. Clear cache directory
  5. Consider moving to larger partition
Regularly check disk space before game updates. Major updates can require 20+ GB temporary space.
