My computer keeps filling up as soon as I empty it. I had it half empty by rubbing out programmes (some I really need ) and old files and emails. I am running virus AVG ,Anti spyware ,disk clean up and when ever I get free space defrag (defraggler seems to work where the microsoft one doesn't). I only have 273 MB free now. I can watch iplayer fine. I have been filing stuff in briefcases on the desk top --maybe I have duplicated something here. I have one briefcase which is 34 GB which I need my son to visit and edit but somehow I seem to have managed to drop it into a free dropbox which I thought only had a small amount of space. I have even tried 40 ways to empty the computer and done all the things i can understand on there. Not sure how to create a batch file.
