My computer is so slow even though I installed extar memory. I don’t know what to delete because I’m not sure if thereare hidden folders underneath that I might need,even if I do delete it you can be sure that it is still hidden somewhere else in my computer. I have to start with, Start, find, files and folders, then enter the name and delete all and hope none of the folders I deleted didn’t have anything to do with any other programs.How do I know what I need in my computer,without abc’s so I can read it?
