Most file systems include attributes of files and directories that control the ability of users to read, change, navigate, and execute the contents of the file system. In some cases, menu options or functions may be made visible or hidden depending on a user's permission level; this kind of user interface is referred to as permission-driven.
The chmod command is also capable of changing the additional permissions or special modes of a file or directory. The symbolic modes use ' s ' to represent the setuid and setgid modes, and ' t ' to represent the sticky mode. The modes are only applied to the appropriate classes, regardless of whether or not other classes are specified.
Changes to files in folders that standard users don't have permissions for (such as %SystemRoot% or %ProgramFiles% in most cases) Changes to an access control list (ACL), commonly referred to as file or folder permissions; Installing and uninstalling applications outside of: The %USERPROFILE% (e.g. C:\Users\{logged in user}) folder and its sub ...
List, backup and restore permissions. All operations work on a single object or recursively on a directory or registry tree. Set the owner to any user or group. Unicode support. Remove, replace or copy a user or group from an ACL. Fast performance due to time-consuming steps such as recursing a large file system are performed only once.
In Unix and Unix-like systems, including POSIX-conforming systems, each file has a 'mode' containing 9 bit flags controlling read, write and execute permission for each of the file's owner, group and all other users (see File-system permissions §Traditional Unix permissions for more details) plus the setuid and setgid bit flags and a 'sticky' bit flag.
The File Types tab has been removed from Folder Options. This feature was available from Windows 95 up to Windows XP and Windows Server 2003. The File Types tab allowed users to change the file associations for various types of files. It allowed configuring which application would open when a user clicked on a certain type of file, or allowed ...
The user-profiling scheme in force today owes its origins to Windows NT, which stored its profiles within the system folder itself, typically under C:\WINNT\Profiles\. Windows 2000 saw the change to a separate "Documents and Settings" folder for profiles, and in this respect is virtually identical to Windows XP and Windows Server 2003.
In Microsoft Windows, cacls, and its replacement icacls, are native command-line utilities that can display and modify the security descriptors on files and folders. [1] [2] An access-control list is a list of permissions for securable object, such as a file or folder, that controls who can access it.
