Encrypting Files on Moto G, implications?

[shmotog]

I wanted to enable file encyption in developer tools menu. From my limited research I understand that doing so would mean if I back up or copy the files to my PC I won't be able to read them. In case I lose my phone, or if it breaks, I would want to be able to view my files on my PC. Is there a way to decrypt my files on PC later on?
