There is no need to explain the importance of doing backup on your Samsung Galaxy phone. And you may lose them in so many ways, including factory reset, accidental deletion, system update, and so on. It is possible that everyone knows how to transfer the data to the internal storage or a SIM card. But do you have any idea how those data can be copied to PC? Worry no more.
You can try to use Samsung Backup Tool to backup and restore data on Samsung. Before this, you might want to stop using the phone for the sake of the files, because they can be overwritten and be gone.
