# File Associations
Pico Launcher supports custom file associations for file extensions other than `.nds`.
By setting up a file association, files with the specified extension will be opened using the specified DS application.
The file path is passed via argv.
## How to setup file associations
1. Open `/_pico/settings.json`.
2. If not present yet, add a `fileAssociations` key.
3. For each file association add a key inside the `fileAssociations` key. For example:
```json
"fileAssociations": {
"xyz": {
"appPath": "/path/to/xyz/app.nds"
},
"gba": {
"appPath": "/myGbaApp.nds"
}
}
```
With this setup `.xyz` files will be opened by `/path/to/xyz/app.nds` and `.gba` files will be opened by `/myGbaApp.nds`.
