Data storage on most PCs is cheap. Or t least cheaper than, say RAM. Adding more is almost never a problem, unless you’re talking about devices with more or less fixed storage capacities and little or no expansion capabilities. Like laptops or tablets. Since Windows 10 has to cater to them all, Microsoft is making it smarter about the way it handles data storage. In the upcoming Windows 10 update, it will make its Storage Sense feature free up even more space by offloading old files to everyone’s favorite dumping ground: the cloud.
