The file is a logical unit of storing information and is processed as a single unit during the processing process. Filename = Ownername. Extension (file type) operating system Windows names The file can have no more than 255 characters (in the file name there may be Latin and Russian letters, lines, dashes, the arrow symbol, dot, hail sign and other symbols). File extension in Windows system, as a rule, is not displayed.

The hard disk consists of tracks, which are divided into sectors.
Description of the presentation with the following slides:
A cluster is a minimally addressing block of disk memory for writing/reading data on a disk drive (hard drive).
A cluster can occupy one or more sectors.
Description of the presentation with the following slides:
The numbers of occupied clusters indicate the “coordinate” of the file for the OS. All files on the disk always have a size that is a multiple of the cluster size.(File Allocation Table – “file allocation table”).
The simplified structure of the “Root Directory” database can be represented in the form of a table: The “Root Directory” DB is a database that stores information about files and folders on the disk.

File system FAT (File Allocation Table - "File Allocation Table").
Description of the presentation with the following slides:
The “FAT Elements” database contains information about disk clusters.
In simple terms, the structure of this database can be represented as follows:

The cluster data is 64 KB, the sector data is 512 bytes, and therefore it is impossible to transfer 128 sectors (65,536: 512 = 128). All files are divided by size into the following categories:
Slide 19
Description of the presentation with the following slides:
Most of the features of NTFS stem from the fact that the file system was designed as a highly reliable system. NTFS, like FAT, distributes the file space in clusters, and the cluster addressing is assigned to the 64th bit, and not 32. All elements of the partition, including services, are considered in NTFS as files with the same set of attributes. Files containing service information are called metadata files or metafiles.
Before such a file there is a master file table (MFT, Master File Table).

Hierarchical.
Description of the presentation with the following slides:
In a hierarchical file system, the formatting process creates a root directory. This can be saved as files and other lower-level directories, called subdirectories or subdirectories. In the Windows operating system, subdirectories are usually called folders.
Drive C: Directories organized in a rich hierarchical structure are also called a directory tree.

The skin catalogue, apart from the root catalogue, is one single “Father’s” catalogue, in the middle of which there is one. 24 slide File system. Hierarchical. You need to know
required file
For hierarchical structure assignments, you must indicate the path to this file.
To do this, you need to indicate the logical name of the disk on which the file is saved, and then, using the \ sign, indicate sequentially all the subdirectories, nested one within the other, where the remaining one will be the subdirectory in which the file was transferred.
For example, in most hierarchies the path to file 1.txt is written as D:\Doc\, and the path to the tetris.exe file is written as D:\Games\Tetris\.

File. Operations with files When working on a computer, you most often have to delete the following operations with files: copying - when deleted, this operation physically creates a new file and a new record in the file system;
relocation - at the end of this operation, the file is physically lost on the disk to a large amount of space, and is changed to its “address” on the file system;

File system.
The new hard drive cannot be used to save information or install programs.
You need to create partitions (volumes) on the disk and start the process of formatting (partitioning) the disk.
You can create one or more partitions (logical drives) on one physical storage device.
Logical drives are assigned the type of great letter of the Latin alphabet (C:, D:, E:, etc.).
Formatting is the creation of a logical disk structure based on a file system. Partitions on one physical device can be formatted with different file systems, and different operating systems can be installed on one physical device.
When the operating system is installed on a new disk, the procedure for creating partitions and formatting the disk follows the same rules as the installation disk.
When an additional disk is inserted, the creation of partitions and formatting of the disk is determined by the operating system.

File system
A large number of files can be stored on a storage device (small, hard or laser disk).
The order in which files are saved on the disk is determined by the installed file system.
A file system is a system for storing files and organizing directories.
For disks with a small number of files (up to several dozen), manually create a peer-to-peer file system if the directory (disk space) has a linear sequence of file names.
To search for a file on disk, you only need to enter the file name.
Since hundreds and thousands of files are stored on the disk, then for the convenience of searching, the files are organized into a rich hierarchical file system, which is a system of nested folders (most often, instead of directories, the concept of “folder” ") Each folder can save lower-level folders, as well as files. Way to file To find a file in the hierarchy file structure You need to enter the directions to the file. « \ »
The path to the file begins with the logical name of the disk (A, B - hard disks, C, D, E, etc. - hard disks \8 optical disks \ .), then the sequence of names of attachments in one folder is recorded, the remainder of which contains the required file. \ The names of the drive and folders are recorded through the separator \ E:

Submission of a file system behind an additional graphical interface The hierarchical file system MS – DOS, which allows to organize directories and files, is presented in the Windows operating system through an additional graphical interface in the form of a hierarchical system of folders and documents.
A folder in Windows is analogous to the MS – DOS directory. However, the hierarchical structure of these systems differs greatly. In the hierarchical file system MS - DOS, the top of the hierarchy of objects is the root directory of the disk, which can be leveled in a tree, on which pins (subdirectories) grow, and leaves (files) grow on the pins. Windows places the Desktop folder at the top of the folder hierarchy. A new wave of views of the folders My Computer, Koshyk and Merezheve Otochenya (as the computer is connected to a local network).
