Here are the steps to move internal storage to SD card on an Android device:

1. Go to **Settings** > **Storage** > **Internal shared storage**.
2. Find and tap **Files**.
3. Touch and hold the folder or file that you want to transfer.
4. Tap the menu icon (three vertical dots) > **Move to... / Copy to...**
5. Tap the menu icon (three horizontal lines), and then tap **SD Card**.
6. Select a destination on the memory card and tap **MOVE / COPY**.

Alternatively, you can format the SD card as internal storage and move data by going to Settings -> Storage -> SD card -> Migrate data.
