This example demonstrates how to utilize the Apps Data folder to store data that is not part of the app itself, such as user data, configuration files, and so forth.
## What is the Apps Data Folder?
The **Apps Data** folder is a folder used to store data for external apps that are not part of the main firmware.
The path to the current application folder is related to the `appid` of the app. The `appid` is used to identify the app in the app store and is stored in the `application.fam` file.
The Apps Data folder is located only on the external storage, the SD card.
For example, if the `appid` of the app is `snake_game`, the path to the Apps Data folder will be `/ext/apps_data/snake_game`. But using raw paths is not recommended, because the path to the Apps Data folder can change in the future. Use the `/data` alias instead.
You can use `/data` alias to get the path to the current application data folder. For example, if you want to open a file `config.txt` in the Apps Data folder, you can use the next path: `/data/config.txt`. But this way is not recommended, because even the `/data` alias can change in the future.
We recommend to use the `APP_DATA_PATH` macro to get the path to the Apps Data folder. For example, if you want to open a file `config.txt` in the Apps Data folder, you can use the next path: `APP_DATA_PATH("config.txt")`.
## What is the difference between the Apps Assets folder and the Apps Data folder?
The Apps Assets folder is used to store the data <u>provided</u> with the application. For example, if you want to create a game, you can store game levels (content data) in the Apps Assets folder.
The Apps Data folder is used to store data <u>generated</u> by the application. For example, if you want to create a game, you can save the progress of the game (user-generated data) in the Apps Data folder.
