Are you careful with files in the safe?

I currently own a Huawei P9 lite with Android 7.0 and have files named "Files in this directory are very important Please do not delete" and, Be careful with files in the safe found in my internal memory under .File_SafeBox.

Would like to know now what these files are good for and what would happen if you deleted them. And - what are these files about the vault?

I suggest you just delete them and then throw the phone away.

Important files such as the operating system are stored in these files. Also renewed certificates and so on are in there.

Oh!
