Hello, on my PC I have a 237 GB Solid state drive with Windows 10 and Office 2007. I also have a 931 Gig Western Digital hard drive with photos and music. Now my solid state drive had plenty of free space, but it has filled up quite fast suddenly with 10.5 Gigs of space left. What is causing this, and what can I do to increase the storage on this ssd ?

Thanks,
