While you’re Surface is unable to expand it’s memory use, it’s possible to expand your storage exponentially via the MicroSD card slot mentioned elsewhere. That being said, it is probably best to use that space to download web version apps as opposed to memory hogging software apps. You can find these in the Microsoft Store and for most others, you can find online or even create from the browser itself. I’ve seen media creation done using specific apps from the Adobe Creative Suite Online. Remember that your Surface (especially older ones) weren’t meant to be a laptop replacement. They were meant to be a Tablet upgrade living somewhere in between a high powered tablet device and low-power laptop.
