Hi Roger, Especially – I repeat – ESPECIALLY where adaptive software is concerned, I would want to examine each and every one of those 142 files before any kind of removal process. These programs are developed for the mass market, and cannot always be guaranteed to be multiple screen reader aware. I’d suggest it’s best to look at specific problems you are having such as speed and performance, and go from there, rather than looking at the root cause, rather than a global generic solution.

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
