Hi, this is my first question on the forums so I'm sorry if this is a common question. My phone (Sony Xperia XZ) is telling me that the internal storage is almost full, and though I have lots of apps, I think i have moved all the ones I can to the SD card. I read about the app Storage Truth, and it tells me that 4.48/5.50GB is used on /system, and 21.23/21.74GB is used on /data/media but when i try to look into the file on both a file manager app and on my laptop, all i can find under /data is (embarrassingly) a file for okcupid how can I find what is eating up so much of my storage, and clear it up? P.S. I'd rather not root my pone if i can avoid it.
