can't copy/create files to C:\ root directory.

my problem is I can't copy/create files to C:\root directory. I only noticed the problem when I wanted to create some files in the root directory.

1) there used to be many options under create "New", there is only "Folder" now.



2) if I click "New Folder" it will give me the below access denied error. so I can't create new folders too. I cannot copy and paste files from the directories to the root, it's the same access denied error.



3) the "New" option looks like this in my sub-directories. I can copy and paste files in the sub-directories, no problems at all.





think my security settings is causing this problem. can't figure out why. I am set to Administrator with full control for everything in security properties. the User Account Settings is set to the lowest levels.

please advise, thank you.

the write option in Group permission: Users, was not allowed. I allowed the write and problem is solved.
