Transferring games from microSD card to Switch’s internal storage is useful when upgrading cards or freeing up SD space. Ensure the microSD card is inserted into the console. Go to 'System Settings' > 'Data Management' > 'Move Data Between System/microSD Card'. Select 'Move to System Memory'—a list of games on the microSD card will appear. Choose the games you want to transfer, then select 'Move Data'. The transfer time depends on game size—small games take minutes, while large titles like 'The Legend of Zelda: Tears of the Kingdom' take 15-20 minutes. Do not turn off the console during transfer to avoid data corruption. Once complete, games will launch from internal storage, and save data remains intact. You can set internal storage as the default download location by going to 'Data Management' > 'Download Location' > 'System Memory'.
