File management
As a file manager (also file management ; english file management ) are in the information technology referred to different operations and processes on computer systems that manage the widest sense files describe. The point of view is the detail, i.e. the level from which it is viewed.
scope
File management in general includes any manipulation of files, including a.
- creating,
- copying,
- naming or renaming (the file name ),
- moving (the path within a hierarchical file system structure, also on other storage media ),
- the deletion ,
- changing metadata (e.g. file attributes ),
mostly within the possibilities of a file system .
Viewing level
operating system
From the point of view of the operating system , file management is one level of the I / O system. Here, files are seen as objects and create unified structures around these objects within the operating system, as part of the programming interface ( English application programming interface to provide short API). The file access and management thus stand on a logical level, also known as virtual file system called so can access the same way out on the operating system running programs without each other in the way to go ( locking of files English Locking ). In the end, it does not matter to the programs in which physical storage location the data of a file is actually stored, since this device-dependent I / O function is performed by the operating system. The file system used plays a central role. Many extended file management functions are mapped in the file system used, such as the provision of metadata or security functions such as journaling and the management of defective data blocks .
programming
In programming, the term describes the management of data if it is held in the form of files. Additional considerations are important here, as the data must be stored in a structured manner so that they can be read in again at a later point in time and used again. An application programmer must therefore also think about the structure of the data storage, from the number of files required, the file names used to the data structure within the files ( file format ).
Most programming languages offer special functions for managing files.
The backup is a form of (automatic) fuse ( English backup ) of a file that is not the operating system, but by the application program is executed.
user
For the computer user , file management generally means the activity of working with files. Mostly one uses file managers for this ( English to manage , lead, accomplish, but English management, among other things, the administration, as in file management as file management). But even on the command line , such as on a terminal , one can speak of file management if files are renamed, moved, copied, deleted or otherwise changed using commands . Changing metadata, e.g. B. the creation time of a file counts as well as making backup copies .
