What is the range file system?

File system range (EFS) is a method of managing files and memory on your hard disk computer or other physical storage device that uses a number of neighboring memory areas to store information instead of using smaller dispersed units known as blocks. Some file systems allocate the space needed for files in small units known as blocks, which may lead to one file of average length is physically dispersed on the disk, reducing the speed and efficiency of reading from this file. In the case of the file range system, all smaller blocks are connected to a larger structure known as the range, which means that larger files can be stored in one adjacent location on the physical disk, which increases the speed of the unit when reading from this file. Although many operating systems support the use of the scope, the term was originally applied to a specific system of the early file system, now completed by the UNIX operating system known as IRIX®, Dev seested by SiliconGraphics®.

Individual bits and bytes on the physical disk, such as a hard disk or compact disk (CD), are divided into groups by hardware, operating system and file system. They are known as logical groups, because they do not necessarily have physical boundaries, only those stored by the system. For several file systems, logical grouping known as blocks is used as the basic amount of space that can be assigned to store a file. The block can be set to any size, but in general it is very small, sometimes consisting of only 128 bytes of space.

The range of file groups blocks together on the disk if they are adjacent, which means they are all physically side by side on the disk. This collection of blocks is known as the scope. In the file range, when the file is written on a physical disk, the scope is assigned instead of the single. The advantage of using the scope instead of blocks is that large files requireLess overhead costs for creating and maintenance and risk of fragmentation are significantly reduced, although not necessarily eliminated.

The fragmentation of the file occurs when the file requires more space than any available block or range, which means that the file must be divided and occupied by two or more physically different spaces on the disk. For small blocks, large files can occupy hundreds or thousands of blocks on the entire disk, reducing the speed at which the file can be accessed. The file system in the range allows you to break a large file to different range, known as the indirect range, although the number of range required is usually less than if the file was assigned using smaller blocks.

In addition to reducing the number of overhead costs for large files, as one range information must be stored in the file system instead of multiple indicators to differ blocks by means of scope can also extend the life of some storage hardware. This may happen because adjacent files require mMovement from the Reading Mechanism of the head of the disk drive to access information. The file range system also allows you to create individual files that can be tertiates or more in length, as in some cases it can theoretically occupy all available physical space without having to create extensive tables or other management overheads.
