It run by itself at the end of day when i close the browser, I use Google Chrome, so it cleans every thing left behind by Chrome, around 400Mb each time.
At the same time it cleans:
windows explorer - recent documents,
system temporary files and clipbord
every thing in ‘multimedia’ tab,
windows defender from ‘Applications’ ‘Utilities’.
I didn’t find any button in Custom Clean , but I hope it also clean ‘windows temp folder’ as I checked it in ‘options - advanced’
Same thing for recycle bin, there is no button into ‘Custom Clean’
I hope it is done since i checked ‘Recycle bin’ into ‘options - advanced’
