Found coding on my phone

Hello . i have no clue what im doing. Know NOTHING about coding. Or anything about technology to be honest. Im lucky i know what www. Means.
I found a whole bunch of config.xml and (whole bunch of random letters and number ) .txt. on a my drive. When i open it its just coding…How do i know what it is? Or what its for? Or how it got on there? Can anyone help me out ?

Hi @samxo420! Welcome to the Explorers Hub. Can I ask if this has anything to do with New Relic or are these just generic config files?

Thank you. To be honest. Im not sure. I just started copying words and web searching them trying to get an idea of something at what i was looking at.
