i have a dell xps 15, with an ssd drive ... was running beautifully then i let it get full.. super full, like less than 1% available.. Naughty i know.. then ive deleted a whole load of stuff and moved it to hard drive . Had to upgrade to cc 2021 and now the thing runs, well limps soooooo slowly.. Any ideas.. Ive run glary , not helping and i shut down often. Also do you defrag an SSD? Thanks or any help
