Hi all, I got my Surface 3 secondhand and have been using it for taking notes in medical school, printing powerpoints to OneNote. Recently, it has started telling me that the memory is close to full. A few times I have not been able to download powerpoints to it because of disc space. I have deleted my downloads, moved all extra files to a 16gb microSD card, cleared my temporary files, deleted a lot of the standard apps. However, it keeps on filling up again in a matter of days. The most frustrating part is that when I check system memory, it tells me that I am using up 32.6 gb in apps and games. However, when I check the specifics, the largest app I have is OneNote at ~3gb, two other microsoft apps clocking in at 2gb each, 6 apps in the megabyte range, and then around 20 that are kilobytes. It does not add up to 32. Are there apps on my device that are not showing?
