Hi. I have a 1 Tb disk, I run Win 7 on a recon PC. Everything runs fine but pc is a bit slow, especially connecting to server. However, even after removing my pics, my disk is still at 870G, and I can't figure out where all that volume is from. I do not view any films. Emptied temp file, a few caches. I have very little experience. Suggestion ? Thanks for your time and stay safe !
