Small neat and very fast, and like all cleaners I would suggest caution although this does provide a comprehensive list and you have the option to set the required fields, first scan and clean I thought was a little slow but that is natural, if your worried about recently opened files then this should do the job fine, overall looks promising and suits me, could turn out to be a promising cleaner looking at the current trend that is windows 10, and if you share a pc or laptop but that is nit-picking, and so-far after a couple of scans for test purposes no side effects and an option not to auto-clean makes this more sound.
