With a C: Partition of 16GB iwas at 11% free and eliminated and uninstalled a world of sh** to come up with 23% free and enough defragmented files to run GHOST basic backup. Guess what? Today I boot and find that the partition is now showing 5% free and no significant new files since last night when I did all the work. I'm new to here but bought IBM chasis #180 - 85 in 1979? so have been around a moment or two. What the h*** happened?
