Trash (computing)

In computing, the trash is a graphical user interface desktop metaphor for temporary storage for set aside by the user for deletion, but not yet permanently erased. The concept and name is part of Mac operating systems, a similar implementation is called the Recycle Bin in Microsoft Windows, and other operating systems use other names. In the , the trash can be viewed by the user as a special file directory, allowing the user to browse the files and retain those still wanted before deleting the others permanently (either one by one, or via an "empty trash" command). It may still be possible using third party software to undelete those that were deleted by mistake. In Microsoft Windows and macOS, the Trash folder links to hidden folders on each mounted drive where the files are actually stored. Within a trash folder, a record may be kept of each file and/or directory's original location, depending on the implementation. 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. Bill Atkinson began developing the Apple Lisa user interface in late 1978. In March 1982 he reached the stage of changing to an icon-based file manager, and produced a mock-up with a trash can icon (including buzzing flies) for deleting files. The release version of Lisa was launched in 1983 with a "Wastebasket", its icon "an alley-style garbage can [with] vertical lines to indicate a ribbed surface .... an open lid and a handle on the front of the can." Apple advertised "If you can find the trash can, you can run a computer." Following this, the Magic Desk I ROM cartridge for Commodore 64 presented a primitive representation of office furniture, with a wastebasket or trash bin under the desk.
