Last Night I tried out a product called spring clean to speed up my imac (later I found out its not a great program) and clean old files out. I left a few things running over night and when I woke up this morning I had a message stating my disk is almost full! I have about 195gb free, but now it says I have 500kb free! Does anyone know what I can do, or where I should look to see where all that free space went?
