Image: Neon sign. Our world is made of elements and combinations of elements called compounds. An element is a pure substance made of atoms that are all of the same type.
Temp folder contains Scoped_Dir folders. My temp folder has only recently started filling up with Scoped_Dir..... Folders. I cannot located the program or service that is causing them. An internet search indicated the folders might be linked to Google chrome or steam but I don't think so.
Temp files are usually files left over from a setup. Sometimes they get cleaned up, but yours should never have been allowed to get to large. Do a search for .tmp files on the system. Select them all> Delete. The only exception is if you have recently in last day or two installed new software. If so, that file should be allowed to remain for up to a week.
