How to use Google drive to store photos/videos/epub fanfic files/documents/stories/book files/Anime/cartoons/movies and not have them on my phones internal storage taking up space?, is Google drive the same as cloud? What is cloud? I only used Google drive in highschool 2014, what can I do to move all the above into Google drive (will it stay in Google drive and not be deleted like stay there permanently even if a they get deleted of the fanfic site or off my phones internal storage?),

I got a 512 SD card, I can put my photos on fine, but when I try to move anime/cartoon files they copy over but stay on my internal storage which is taking up space and I deleted them they deleted off the SD card as well when I did (I have them backed up on the app) but I would like to completely transfer them to download more episodes of others shows), never really used a SD card before, any tips?, any good 2tb or high SD cards I can put phone with dual sim slots (the phone I plan on getting says that they can be used because other people reviews have done 2 tb twice and they worked in the phone).
