I Apologise in advance, if my question sounds nerdy. It's just that i dont want to have extra space taken up by unwanted files. I have recently been using the Files app quit a lot and am now wondering, about the files downloaded from inside the Files app in ios only for viewing. These files do not have the cloud with an arrow icon after i have pressed on them in order to view them (lets say it's a photo), so it seems that the Files app downloads these photos to my device, but where does it store these photos? I mean its obvious that it should be in the photos app, but no, it is only there if I specifically save it to the photos app. But where are these photos downloaded to from the cloud in first place from them to be viewed inside the Files app? And if there is some kind of a cache folder how to empty it or reupload these photos back to icloud.
