I use Auslogics defrag program. I’ve just run it and once again it tells me I have junk files. This time 142 on a 250 gig primary hard drive. Firstly is this a problem I need to worry about or it is really a way of Auslogics promoting their BoostSpeed software. If it is any sort of problem is there any free software that will do the job for me, please? Many thanks Roger
