In the Microsoft Windows operating system s, the Recycle Bin is a holding area for files and folders before final file deletion deletion from a storage device. Image Windows Recycle Bin.png right thumb Recycle Bin in Windows Vista . General Commented out because image was deleted Image Recyclebinempty.PNG thumb right An empty recycle bin in Windows Vista. Microsoft introduced the Recycle Bin in the Windows 95 operating system. The Recycle Bin keeps some files that have been deleted, whether accidentally or intentionally. Whether a deleted file is put into the Recycle Bin depends on how it is deleted typically only files deleted via the Windows Explorer Explorer graphical user interface graphical interface but not necessarily other Windows graphical interfaces such as file selection dialogs will be put into the Recycle Bin files deleted via the Command Prompt Windows Command Prompt are permanently deleted, as by default are files deleted via operating system Application Programming Interface APIs and applications other than Windows Explorer. Some operating system APIs do, however, allow applications to recycle files rather than delete them ref http stackoverflow.com questions 17612 how do you place a file in recycle bin instead of delete ref . Users can review the contents of the Recycle Bin before deleting the items permanently. In previous Windows operating systems and in MS DOS, undeletion was the only way to recover accidentally deleted files. The Recycle Bin holds data that not only lists deleted files, but also the date, time and the path of those files. The Recycle Bin is a Special Folders special folder . Deleted files may be removed from the Recycle Bin by restoring them with a command, or by deleting them permanently.

Typically, a recycle bin is presented as a special file directory to the user whether or not it is actually a single directory depends on the implementation , allowing the user to browse deleted files, undeletion undelete those that were deleted by mistake, or delete them permanently either one by one, or by the Empty Trash function . Within a trash folder, a record is kept of each file and or directory s original location. On certain operating systems, files must be moved out of the trash before they can be accessed again. Whether or not files deleted by a program go to the recycle bin depends on its level of integration with a particular desktop environment and its function. Low level utilities usually bypass this layer entirely and delete files immediately. A program that includes file manager functionality may or may not send files to the recycle bin, or it may allow the user to choose between these options.

About the American computer guru other people named Peter Norton Peter Norton disambiguation Peter Norton born November 14, 1943 is an United States American programmer , software publisher , author , and philanthropist . He is best known for the computer programs and books that bear his name. Norton sold his PC Software business to Symantec Corporation in 1990. Career Norton was born in Aberdeen, Washington and raised in Seattle . He attended Reed College in Portland, Oregon , graduating in 1965. Before discovering microcomputer s, he spent a dozen years working on mainframe computer mainframes and minicomputer s for companies including Boeing and Jet Propulsion Laboratory . His earliest low level utility software system utilities were designed to allow mainframe programmers access to some previous Random access memory RAM that IBM normally reserved for diagnostics. This foreshadowed his personal computer work, where he became known as a savvy author of low level system utilities and reference books. When the IBM PC made its debut in 1981, Norton was among the first to buy one. After he was laid off during an aerospace industry cutback, he took up microcomputer programming to make ends meet. One day he accidentally erased a file. Rather than re enter the data, as most would have, he decided to write a program to recover the information from the disk. His friends were delighted with the program and he developed a group of utility programs that he sold one at a time to user groups. In 1982, he founded Peter Norton Computing with 30,000 and an IBM computer. ref Software pioneer s fortune at stake in divorce litigation, Los Angeles Business Journal , May 19, 2003 ref The company was a pioneer in DOS based utilities software. Its 1982 introduction of the Norton Utilities included Norton s popular UNERASE tool to Undeletion retrieve erased data from DOS disks.

The current version 14 of Norton Utilities Premier Edition for Windows XP Vista 7 was released October 14, 2009. Peter Norton published the first version for DOS , The Norton Utilities, Release 1 , in 1982. Release 2 came out about a year later, subsequent to the first hard drives for the IBM PC line. Peter Norton Computing Peter Norton s company was sold to Symantec in 1990. However his name remains as a brand for Symantec s range of utility and security software for home users. Norton Utilities for DOS Windows 3.1 1.0 The initial 1982 release supported DOS 1.x and featured the UNERASE utility. This allowed files to be undeletion undeleted by restoring the first letter of the directory entry a feature of the File Allocation Table FAT file system used in MS DOS , albeit one that was not originally documented . The UNERASE utility was what launched NU on its path to success. Quoting Peter Norton, Why did The Norton Utilities become such popular software? Well, industry wisdom has it that software becomes standard either by providing superior capabilities or by solving problems that were previously unsolvable. In 1982, when I sat down at my PC to write Unerase, I was solving a common problem to which there was no readily available solution. ref Krumm, R. 1990.
