I have a HP Stream 14-cb1xxx. It's running 4GB of memory, with 30GB of storage space (all full). I only have maybe 3 apps I use (Firefox and 2 trading software programs). At this point, it's so full, I cannot even add software or Windows upgrades. Is it possible to put a bigger HD and more memory in this?
It appears there is a slot for an SD card. You could use that slot to store the personal files that are now taking up space on your internal storage space (but it will be slower). Have you tried to clean up files with Settings/System/Storage?
