Hello, I purchased a Samsung notebook with an Intel core 13 processor, and 500GB. In the past 2 months, with NO downloads or large files saved, my C drive has gone from 230GB free to OGB and I dont know why!!! I moved some files into the 330GB D drive but I still have no disk space. Should I wipe and reinstall Windows & or what?? FREAKING OUT.. fyi, I need basic instructions as I am not computer literate, lol.
