First question, the winre.wim file is at 96% fragmented and I cannot defrag the system information folder. How can I get that fragmented file to defrag?

Second question, I have unchecked the hidden system folder so I can try and delete the system volume folder, which didn't work either, now I recheck the settings so the hidden files are hidden but now the system information folder is still showing, it won't go back to hidden, now what?

Thanks for and help.
