Littered throughout my C: are hundreds of files (.bin, .tlb, .cva, .config, .iss, etc.), marked by a blank white icon, which will not open. If you attempt to open them, it is suggested that you use the web to find the appropriate tool to veiw the file. Are these files important, or can I delete them from my C: without consequence? Please make sure replies are 100% correct. I will appreciate any help.
