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.
A robots.txt file contains instructions for bots indicating which web pages they can and cannot access. Robots.txt files are particularly important for web crawlers from search engines such as Google. A robots.txt file on a website will function as a request that specified robots ignore specified files or directories when crawling a site.

This is done because it is the account name, not the behavior of the person behind it, that is the problem. While it is possible to request a change in username, this takes a little longer and requires that a user with global rename access do so. Whichever method you choose, it is a good idea to have some review of the proposed new username ...
If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the resource. The control panel also ignores an opening signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted. [5]
Some file systems, such as Btrfs, HAMMER, ReFS, and ZFS, use internal data and metadata checksumming to detect silent data corruption. In addition, if a corruption is detected and the file system uses integrated RAID mechanisms that provide data redundancy, such file systems can also reconstruct corrupted data in a transparent way.

A temporary file is a file created to store information temporarily, either for a program's intermediate use or for transfer to a permanent file when complete. [1] It may be created by computer programs for a variety of purposes, such as when a program cannot allocate enough memory for its tasks, when the program is working on data bigger than the architecture's address space, or as a ...
The archive files produced by ARC had file names ending in ".ARC" and were thus sometimes called "arc files". The source code for ARC was released by SEA in 1986 and subsequently ported to Unix and Atari ST in 1987 by Howard Chu. This more portable codebase was subsequently ported to other platforms, including VAX/VMS and IBM System/370 mainframes.
