Files Doesn't Show in Flash Drive H:\AutoRun.inf

Hi,
I have these files saved in my flash drive that I can't open. I've already checked the folder options to see if the option "show hidden files, folders and drivers" is selected and it is. I also tried the command prompt option (RUN then type CMD then press enter
then change the directory. Go to the directory of the flash drive then type ATTRIB -S -H *.* /S /D press enter) then got this message "Access denied - H:\AutoRun.inf". What should I do next? Please help. Thanks!
