ReFS was also introduced by Microsoft as a new generation format for server computers starting from Windows Server 2012. Microsoft Windows employs two major file systems: NTFS, the primary format most modern versions of this OS use by default, and FAT, which was inherited from old DOS and has exFAT as its later extension. To comply with diverse users' requirements, such as storage performance, stability and reliability, plenty of FS types (or formats) are developed to be able to serve different purposes more effectively. It may also store security information, extended attributes and other parameters. In addition to the user's data, the file system also contains its own parameters (such as a block size), file descriptors (including its size, location, fragments, etc.), names and directory hierarchy. The information about both fragments as its parts is stored in the file system.

In this case, the 8-block file is split into two parts (4 blocks for each part) and takes the free space "holes". By doing this, he or she frees the space of 8 blocks, however, the first segment is located near to the storage start while the second one – to the storage end. A user wants to store one that will take up 8 blocks, and therefore deletes the first and the last files. For example, a volume is completely occupied by files with the size of about 4 blocks each (e.g. Thus, files are not stored as whole units, but get divided into fragments. Files are usually stored at the start of a block and take up entire blocks.Ĭonstant write/delete operations within a storage cause its fragmentation. Modern types generally use block sizes from 1 to 128 sectors (512-65536 bytes). FS blocks are groups of sectors that optimize storage addressing. Usually, it operates in blocks, not sectors.
This structure serves for the purposes of the whole storage and is also a part of an isolated storage segment – a disk partition. It is applied to the storage during the format operation. However, how do we know which sectors are occupied and which are free? Where are the size, position and name of the file stored? This is exactly what the file system is responsible for.Īs a whole, the file system (often abbreviated as FS) is a structured representation of data and a set of metadata describing this data. To omit the second part of the address (in-sector offset), files are usually stored starting from the sector start and occupy whole sectors (e.g.: a 10-byte file occupies the whole sector, a 512-byte file also occupies the whole sector, at the same time, a 514-byte one occupies two entire sectors).Įach file is stored in " unused" sectors and can be read later by its known position and size.
This scheme is applied to optimize storage addressing and to use a smaller number to refer to any portion of information located on the storage. For example, byte 1040 on a hard disk drive will be referenced as a sector #3 and offset in sector 16 bytes (++). A sector is a group of bytes (usually 512 bytes), a minimum addressable unit of the physical storage. Generally, computer storages use the pair of a sector and in-sector offset to reference any byte of information on the storage.
Any item saved to the storage gets its own cells. A storage can be presented as a grid with a set of numbered cells (each cell is a single byte).
Each byte of information on it has its offset from the storage start known as an address and is referenced by this address. In actual fact, each storage is linear space for reading or both reading and writing digital information. Any computer file is stored on a storage medium with a given capacity.
