Hi I am running windows 98se and am on a mission of clear up. But am not sure what I can delete. I go into programs-window explorer-temp internet files. Here there is a sub folder called 'Content.1E5' which then lists 8vhm9kym, C12z0567,C9a3kpub,Eev8cs5n,Kd2ngt23,S5if8xer,U8alflw8,Yp4rudw1. Each one of these folders have a whole load of stuff in I dont understand!! Also there is Index 2,128KB DAT file, what is that? Can I delete this stuff or not?
