File size is a measure of how much data a computer file contains or, alternately, how much storage it consumes. Typically, file size is expressed in units of measurement based on the byte . By convention, file size units use either a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).
Max file size: 4,294,967,295 bytes (4 GB − 1) File size granularity: 1 byte: Max no. of files: 65,536 for 32 KB clusters: Max filename length: 8.3 filename with OEM characters, 255 UCS-2 characters when using LFN: Max directory depth: 32 levels or 66 characters (with CDS), 60 levels or more (without CDS) Features; Dates recorded
Kilobyte. The kilobyte is a multiple of the unit byte for digital information . The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1000 (10 3 ); therefore, one kilobyte is 1000 bytes. [1] The internationally recommended unit symbol for the kilobyte is kB. [1]
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
For each file, exFAT uses two separate 64-bit fields in the directory: the valid data length (VDL), which indicates the real size of the file, and the physical data length. To provide improvement in the allocation of cluster storage for a new file, Microsoft incorporated a method to pre-allocate contiguous clusters and bypass the use of ...
In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs and DVD-ROMs. Newer HDDs and SSDs use 4096-byte (4 KiB) sectors, which are known as the ...
Data compression. In information theory, data compression, source coding, [1] or bit-rate reduction is the process of encoding information using fewer bits than the original representation. [2] Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy.
File format. wav-file: 2.1 megabytes. ogg-file: 154 kilobytes. A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or free .
