- File and Folder Permissions
Administrator accounts are the only ones who can view folders at will, as when anyone wants to view another person's "User" folder, they need administrative privileges to do so.
All of the folders on the PC are viewable by any user unless explicitly denied privileges, obviously with the exception of the "Users" folder.
The "Program Files" folders and the Windows directory (or wherever Windows is installed to) can only be modified by someone with administrative access, and by default, is owned by a special user named "TrustedInstaller". The "Users" folder is owned by the system, and the rest (in general) are owned by whomever created them.
Additionally, you can find out who actually owns a folder by right clicking the folder, going to properties, clicking the "Security" tab, and hitting the "Advanced" button. Near the top, it will tell you who owns the folder/file.
