2. File size - Wikipedia

   en.wikipedia.org/wiki/File_size

   File size. 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 ).

3. exFAT - Wikipedia

   en.wikipedia.org/wiki/ExFAT

   exFAT ( Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards. [6] exFAT was proprietary until 28 August 2019, when Microsoft published its specification. [7] Microsoft owns patents on several elements of its design. [2]

4. NTFS - Wikipedia

   en.wikipedia.org/wiki/NTFS

   In NTFS, all file, directory and metafile data—file name, creation date, access permissions (by the use of access control lists), and size—are stored as metadata in the Master File Table (MFT). This abstract approach allowed easy addition of file system features during Windows NT's development—an example is the addition of fields for ...

5. Image file format - Wikipedia

   en.wikipedia.org/wiki/Image_file_format

   Image file format. An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy ...

6. Comparison of file systems - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_file_systems

   While storage devices usually have their size expressed in powers of 10 (for instance a 1 TB Solid State Drive will contain at least 1,000,000,000,000 (10 12, 1000 4) bytes), filesystem limits are invariably powers of 2, so usually expressed with IEC prefixes.

7. File Allocation Table - Wikipedia

   en.wikipedia.org/wiki/File_Allocation_Table

   File Allocation Table. File Allocation Table ( FAT) is a file system developed for personal computers and was the default filesystem for MS-DOS and Windows 9x operating systems. [3] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.

8. Data compression - Wikipedia

   en.wikipedia.org/wiki/Data_compression

   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.
