help in moving apps to external
Go to Settings | Apps and tap the app you'd like to move. If there's a "Move to SD card" button there and it's lit up, you can move the app to the SD card. Tap the button and it'll start the process.

Note:


Not all apps can be moved the SD card
Even if you move the app to the SD card, some of it will remain in internal storage
Apps on the SD card will not work when your device is connected to a computer via USB


(This also assumes you're using a device and version of the OS that supports moving apps to the SD card. I'm not talking about custom ROMs that let you use the SD card as if it was internal storage.)

Back when I had a device with an SD card, two of my most critical apps were SDMove and SDWatch.

SDMove gives you a consolidated list of all the apps that can be moved to the SD card and links to the app info page so you can do that. SDWatch checks an app when it is installed to alert you if it can be moved to the SD card.
