By default, apps are installed on the internal memory, and all the data and files created by the app are also stored on it.

If the Samsung device supports memory expansion, we can move the app to the memory card.

Unfortunately, it is not yet possible to install directly to the memory card.

Note: Moving to the memory card must be supported by the app.
